Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a display panel bonding method and apparatus for bonding two glass substrates (light-transmitting substrates) with a photocurable sealing agent in a display panel assembly process.
[0002]
[Prior art]
In recent years, a drop method (One Drop Fill) has been adopted as a method for manufacturing a liquid crystal display element as disclosed in Japanese Patent Laid-Open No. 9-73096.
In this construction method, a glass substrate (light-transmitting substrate) as shown in FIG. 9 is formed with a sealant which is an ultraviolet curable resin, liquid crystal is dropped therein, and the liquid crystal is dropped on the glass substrate. Another glass substrate is placed on the glass substrate, and the sealing agent is cured by irradiating the sealing agent with ultraviolet rays through the glass substrate, and the two glass substrates are bonded together. When irradiating the sealant with ultraviolet light, if the liquid crystal is irradiated with ultraviolet light, the liquid crystal will decompose and change its properties. A light-shielding mask is provided between and UV rays are irradiated.
[0003]
As the ultraviolet irradiation apparatus for curing the sealant, an apparatus for irradiating light to the entire glass substrate is used. However, the liquid crystal display panel is getting larger year by year, and the glass substrate is also getting larger, for example, from 730 mm × 930 mm to 1 The one whose side exceeds 1m is used. When the glass substrate is increased in size, the lamp used for the ultraviolet irradiation device is also increased in size. With the increase in size of the lamp, the power consumption is increased and the entire apparatus is also increased in size.
[0004]
The light-shielding mask is formed with a light-transmitting part so that only the part corresponding to the sealant transmits ultraviolet light, and the other part is formed with a light-shielding part so as to shield light. Such a shading mask is usually made by applying a chrome plating to a shading portion on a quartz plate, and when the glass substrate is enlarged, the shading mask is also enlarged accordingly, and the production cost for that becomes very high, This increases the cost of the device.
[0005]
Japanese Patent No. 2908259 proposes an apparatus for curing a sealing agent by irradiating spot light made of ultraviolet rays directly through a glass substrate while moving along the sealing agent. This apparatus has advantages that the power of the lamp is increased and the apparatus is not enlarged, and that an expensive light-shielding mask is not required.
[0006]
[Problems to be solved by the invention]
However, the apparatus disclosed in the above-mentioned patent publication has advantages that the lamp can be reduced in electric power and the apparatus can be reduced in size, and an expensive light-shielding mask is not required, but the spot light is moved along the sealant. Since the sealing agent is cured by irradiation, the sealing agent is cured with a time difference, and therefore, there is a disadvantage that distortion occurs in the gap between the two glass substrates.
[0007]
In particular, in recent years, as described above, liquid crystal display panels have become larger year by year, and those with a side exceeding 1 m have been used. Appears as distortion.
[0008]
In view of the above problems, an object of the present invention is to provide a display panel bonding method and apparatus in which distortion is not generated in the gap between two glass substrates.

A light irradiating part containing a light source, an optical fiber for guiding light from the light irradiating part, and an emitting part for emitting spot light from the optical fiber, formed between the glass substrates , in a first direction and It corresponds to the sealing agent having a plurality of rows formed in a second direction perpendicular to the first direction, comprising at least as many emitting portion columns extending in a second direction in each column, the plurality of a spot light simultaneously emitted from the emitting portion, so as to illuminate while moving the sealing agent to the spot beam emitted simultaneously from the while moving the formed direction of the sealant irradiation, or the plurality of emitting portions A display panel bonding apparatus characterized by the above. The emission unit comprises two exit aperture for emitting a spot beam for irradiating each of the sealant formed adjacent to each other, depending on the spacing of arrangement of the sealant which is formed adjacent to each other 6. The display panel bonding apparatus according to claim 4, further comprising an emission hole position setting unit capable of setting an interval between the two emission holes. The emission unit comprises three exit aperture for emitting a spot beam for irradiating each of the sealing agents that are formed adjacent to each other, the first direction of the array of sealant the formed adjacent to each other An emission hole position setting means capable of setting an interval between the three emission holes in accordance with an interval between the sealing agents and an interval between sealing agents arranged in a second direction different from the first direction; 6. An exit hole selecting means for selecting the exit hole that emits spot light in response to irradiation of the formed sealing agent or irradiation of the sealing agent formed in the second direction. The display panel bonding apparatus according to the description.
