け、その圧力差によって液晶の封入を行う方法である。Conventionally, there is a vacuum sealing method h'-- which is the most common method for sealing nematic liquid crystals and smectic liquid crystals between a pair of substrates. This method involves uniformly scattering space materials such as spheres or cylindrical particles with the same diameter as the target cell gap onto one substrate, and then pre-cutting large squares (hereinafter referred to as injection holes) for liquid crystal injection. 5. Next, print the sealing material on the cylindrical plate that will be bonded to one of the substrates, and then apply equal pressure to the cylindrical substrate to create an empty cell sheet. Next, in order to fill the empty cell with liquid crystal, the inside and outside of the cell are made vacuum-like, and the liquid crystal is introduced into the injection hole. After that, the pressure inside the cell is brought to atmospheric pressure or above atmospheric pressure, This is a method in which a pressure difference is provided outside and liquid crystal is encapsulated using the pressure difference.

制御の面から、制限がある。[Problems with invention h: y + determination 5] However, in the above-mentioned prior art, the smectic liquid crystal is used as the main purpose, and the liquid crystal electro-optical element is used as the object. If the diameter of the liquid crystal is 3 microns or less, even if the entire panel is kept at a high temperature to reduce the viscosity of the liquid crystal and the liquid crystal is transitioned to an isotropic liquid phase for encapsulation, the encapsulation speed will still be within the liquid crystal encapsulation range. is 50×
A 20 cm cell requires more than 6 hours of encapsulation time, which increases the productivity of liquid crystal electro-optical devices. It's very bad. In order to shorten the encapsulation time, increasing the area of the encapsulation hole has been attempted, but there are limitations in terms of cell gap control.

When filling the liquid crystal, by keeping the entire panel at a temperature, as shown in Figure 3, the liquid crystal compound efficiently collects in the injection hole due to capillary action and spreads uniformly throughout the chamfered piece.

According to the present invention, even if the number of injection holes is increased, the injection time is 2 to 3 times faster, and it takes 3 hours instead of 9 hours to fill a 20 x 50 cm square panel. Using a similar method, smectic liquid crystal can be encapsulated in a short time.
