In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments.
The first embodiment:
referring to fig. 1 and 2, in an embodiment of the present invention, an array substrate 100 is provided, which includes a first substrate 110, a routing layer 120, and a color photoresist layer 140 stacked in sequence. Specifically, the array substrate 100 further includes an insulating layer formed between the routing layer 120 and the color photoresist layer 140, a planarization layer 150 formed on the color photoresist layer 140, and an electrode layer 160 formed on the planarization layer 150. The PI layer is formed on the electrode layer 160 and in contact with the spacer formed on the counter substrate. The electrode layer 160 includes a pixel electrode and a common voltage signal line. The pixel electrode and the common voltage signal line are made of a transparent conductive material ITO (Indium tin oxide).
The routing layer 120 includes scan lines 121 and common traces 122 disposed at intervals. Specifically, the wiring layer 120 further includes a data line 123 and a TFT (Thin Film Transistor). The scan lines 121 and the data lines 123 are insulated from each other and cross to define a plurality of pixel regions arranged in an array. The TFT is located in the pixel region, and includes a Gate (Gate) layer, a Gate Insulator (GI) layer 126, an active layer, and a Source Drain (SD) layer 125, which are sequentially disposed. The gate layer has a gate 124, the gate 124 is connected to the scan line 121, the source drain layer 125 has a source and a drain, the drain is electrically connected to the pixel electrode, and the common trace 122 and the gate 124 of the TFT are located on the same layer and electrically connected to the common voltage signal line.
The color filter layer 140 includes a filter layer 141 and a light shielding layer 142. The light-shielding layers 142 are disposed above the scan lines 121 in a one-to-one correspondence manner, and are used for blocking light. Specifically, the filter layer 141 includes a red filter unit, a green filter unit, and a blue filter unit respectively corresponding to different pixel regions. The light-shielding layer 142 is generally formed by laminating two of a red filter layer, a green filter layer, and a blue filter layer, and preferably a red filter layer and a green filter layer. And the light-shielding layer 142 covers the opposite top regions of the spacers formed on the opposite substrate.
At least one side of the light-shielding layer 142 corresponding to the position 500 of the spacer has a light-shielding portion 143, and the light-shielding portion 143 extends toward the filter layer 141. Specifically, the light shielding portion 143 may be formed integrally with the light shielding layer 142, or may be provided separately from the light shielding layer 142. And the light shielding portion 143 has a different color from the filter unit corresponding to its own position. In order to reduce the light emergence rate of the light through the combined structure of the light-shielding portion 143 and the corresponding filter unit, the light-shielding portion 143 generally extending to the red filter unit is made of a green filter material or a blue filter material; the light shielding portion 143 extending to the green filter unit is made of a red filter material or a blue filter material; the light shielding portion 143 extending to the blue filter unit is made of a green filter material or a red filter material.
The common trace 122 has an extension portion 130 corresponding to the light shielding portion 143, a projection of the extension portion 130 on the first substrate 110 at least partially overlaps a projection of the light shielding portion 143 on the first substrate 110, and an outline of an orthographic projection of the extension portion 130 on the first substrate 110 is located outside a boundary line of a shift range of the corresponding spacer. Specifically, due to the limitation of the manufacturing process, the size of the extension portion 130 is different from that of the light shielding portion 143, and the size of the extension portion 130 is generally larger than that of the light shielding portion 143, as shown in fig. 2 to 10. Thus, the extension portion 130 can effectively support the whole light shielding portion 143, can ensure the stress balance of the spacer 223 in the corresponding area of the light shielding portion 143, and can shield light when the spacer scratches the PI layer, thereby achieving multiple purposes.
In the array substrate 100 provided in this embodiment, at least one side of the light shielding layer 142 corresponding to the position opposite to the spacer is provided with the light shielding portion 143 extending toward the filter layer 141, the light shielding portion 143 and the filter layer 141 are combined to form a light shielding structure, meanwhile, the extension portion 130 is additionally disposed on the side of the common trace 122 away from the scan line 121, the projection of the extension portion 130 and the light shielding portion 143 on the extension portion 130 at least partially overlaps, and the outline of the orthographic projection of the extension portion 130 on the first substrate 110 is located outside the boundary line of the offset range of the corresponding spacer. By adopting the structure, the stress of the spacer in the area corresponding to the original shading layer 142 is equivalent to that of the area corresponding to the newly added shading part 143, so that the sliding probability of the spacer to the filtering layer 141 can be effectively reduced, and the risk of scratching the PI layer can be reduced, and in addition, the arrangement of the shading part 143 and the epitaxial part 130 can also shield the light in the respective corresponding areas when the edge of the PI layer is scratched, so that the light is prevented from being emitted out of the array substrate 100, and the display panel using the array substrate 100. Moreover, since the outline of the orthographic projection of the extension portion 130 on the first substrate 110 is located outside the offset range of the corresponding spacer except the boundary line, the common trace 122, the extension portion 130, the light shielding layer 142, the light shielding portion 143 and other structures on the array substrate 100 capable of shielding light can cover most of the offset range of the spacer, so that the array substrate 100 provided by this embodiment has an excellent light leakage prevention effect, and the quality of the array substrate 100 and the display panel and the display device using the array substrate 100 is effectively improved.
Second embodiment:
referring to fig. 3 and 4, in the first embodiment, an outer contour line of an orthographic projection of the extension portion 130 of the present embodiment on the first substrate is at least partially an arc 131, and the arc 131 is aligned with a boundary line 170 of a shift range of the corresponding spacer.
Thus, the extension portion 130 can extend to the boundary line 170 of the offset range of the spacer, and the unnecessary aperture ratio can be reduced without wasting material.
The third embodiment:
referring to fig. 5 to 8, in the first embodiment, an outer contour line of an orthogonal projection of the extension portion 130 in the present embodiment on the first substrate has at least one first straight portion 132, and the first straight portion 132 is tangent to a boundary line 170 of an offset range of the corresponding spacer. Thus, the array substrate 100 can be ensured to have good light leakage prevention effect, and the bad influence of the overlarge extension portion 130 on the aperture ratio can be avoided.
The array substrate 100 provided in this embodiment includes a plurality of implementation manners:
in a first implementation manner, as shown in fig. 5, when the number of the first straight portions 132 is one, the outer contour line of the orthographic projection of the outer extension portion 130 on the first substrate further has a second straight portion 133, the second straight portion 133 is connected to the first straight portion 132, and the inclination angle of the second straight portion 133 is consistent with the inclination angle of the corresponding pixel electrode.
Second implementation, as shown in fig. 7, when the number of the first straight portions 132 is two, two first straight portions 132 are connected to each other to form an obtuse angle structure. The opening of the obtuse angled structure is directed towards the central region of the offset range of the spacer. And the two first straight portions 132 are consistent with the center-to-center spacing of the offset range of the spacer.
Wherein the second implementation has a higher aperture ratio than the first implementation.
The fourth embodiment:
since the spacer includes the main spacer and the auxiliary spacer, and the solutions in the third embodiment are only suitable for the auxiliary spacer, and the main spacer cannot completely block light, this embodiment provides an extension design solution suitable for the main spacer. Referring to fig. 9 and 10, on the basis of the third embodiment, in the present embodiment, the light shielding portions 143 are disposed on two sides of the corresponding region of the opposite positions 500 of the light shielding layer 142 and the spacer, the common traces 122 disposed on two sides of the scan line 121 and the corresponding region of the spacer 223 have the extension portions 130, and the extension directions of the extension portions 130 on the common traces 122 disposed on two sides of the same scan line 121 are opposite. Therefore, the better light shading effect can be achieved without sacrificing more aperture opening ratios.
In order to avoid the increase of the thickness of the partial area of the color photoresist layer due to the addition of the light shielding portion in the above embodiments, referring to fig. 2, a step portion 144 extending toward the light shielding layer 142 is formed on the side where the filter layer 141 and the light shielding layer 142 are connected, the light shielding portion 143 is mounted on the step portion 144, and the top surface of the light shielding portion 143 is flush with the top surfaces of the filter layer 141 and the light shielding layer 142. Thus, the thickness of each region of the color photoresist layer 140 can be ensured to be equal, the processing is convenient, and the aesthetic degree of the array substrate 100 is not affected.
In order to ensure that the light shielding effect of the light shielding structure is good and the light shielding portion and the corresponding filtering unit have a small thickness after being stacked, in the above embodiments, the filtering layer includes a red filtering unit, a green filtering unit and a blue filtering unit respectively corresponding to different pixel regions. The light shielding portion includes a red filter layer laminated with the blue filter unit, and a blue filter layer laminated with the green filter unit and the red filter unit. That is, if the filter layer corresponding to the top area of the spacer is a red filter unit, the light-shielding part extending to the filter layer is a green filter layer, and if the filter layer corresponding to the top area of the spacer is a green filter unit or a blue filter unit, the light-shielding part extending to the filter layer is a red filter layer.
