改良に関する。DETAILED DESCRIPTION OF THE INVENTION <Technical Field> The present invention relates to an improvement in a method for manufacturing a liquid crystal display element by bonding two substrates, at least one of which is a plastic film substrate, and filling the space between the substrates with liquid crystal.

基板の両面からプレスする工程が必要であつた。<Prior art> Conventionally, in the manufacturing process of a liquid crystal display element in which two thin plastic film substrates are bonded together and liquid crystal is filled between the substrates, a sealing material is printed on the periphery between the two thin plastic film substrates. Meanwhile, it was necessary to disperse spacers over the entire surface and press the two thin plastic film substrates from both sides using a press plate.

子において表示不良が生じた。 Conventionally, however, a glass plate with a smooth surface has been used as the press plate, so the plastic film substrate and the glass plate are in close contact with each other. When heating was carried out, stress was applied between the parts of the plastic film substrate and the glass substrate that were in close contact with each other and the parts that were not in close contact with each other due to thermal expansion of the plastic film substrate. As a result, curls and waviness occur in the plastic film substrate, and abnormal optical anisotropy occurs in the plastic film substrate itself, resulting in display defects in the liquid crystal display element.

液晶表示素子について適用が可能である。 The drawings are explanatory diagrams showing the manufacturing process of one embodiment of the method for manufacturing a liquid crystal display element according to the present invention. In the figure, 1 and 1 are thin plastic film substrates with a thickness of about 0.1 mm. A sealing material 2 is printed on the periphery between the two thin plastic film substrates 1, 1, and spacers 3 such as glass fibers are dispersed over the entire surface thereof. 4, 4 are press glass plates for pressing the two thin plastic film substrates 1, 1 from both sides. A large number of minute plastic beads 5 (for example, Micropearl SP-209 manufactured by Sekisui Fine Chemical Co., Ltd.) are scattered between the press plates 4, 4 and the plastic film substrates 1, 1. Due to the presence of the minute plastic beads 5, the press plates 4, 4 and the two thin plastic film substrates 1, 1 do not come into close contact with each other. Therefore, in the pressed state, the plastic film substrates 1, 1
Even when heating is performed to harden the sealing material 2 between the plastic film substrates 1, 1, no local stress is applied. Therefore, curls and undulations may occur in the plastic film substrates 1, 1.
No abnormal optical anisotropy occurs. Therefore, good display quality can be obtained.
In the above embodiment, both substrates are thin plastic film substrates, but the present invention can be applied to a liquid crystal display element in which at least one of the substrates is a plastic film substrate.
