Embodiment 1
[0062] On the whole of the transparent electrodes 2 and 7 formed on the transparent substrates 1 and 8 made of glass, utilize the polyimide alignment film coating JALS-204 produced by JSR Co. ℃ drying and hardening in a constant temperature bath for 1 hour. Thereafter, polarized ultraviolet light with a wavelength of 365 nm was irradiated for 5 minutes at an angle of 30° away from the normal direction of the substrate.
[0063] The first and second alignment films are opposed so that liquid crystal molecules can be given a certain Brewster angle in the same direction, and the spacer 5 manufactured by Sekisui Fine Chemical Co., Ltd. is used to make the substrate interval 6.5 μm The ground was bonded with Strat adhesive 352A manufactured by Mitsui Topress Chemical Co., Ltd., to form a liquid crystal cell 9 (liquid crystal cell A).
[0064] Similarly, the irradiation time of above-mentioned polarized ultraviolet light is respectively 10 minutes, 15 minutes, 20 minutes, 25 minute...
Embodiment 2
[0073]Adopt the same way as embodiment 1, make and figure 1 The same liquid crystal pixel M.
[0074] On the whole of the transparent electrodes 2 and 7 formed on the transparent substrates 1 and 8 made of glass, utilize the polyimide alignment film coating JALS-204 produced by JSR Co. It was dried and hardened in a constant temperature bath for 1 hour.
[0075] Thereafter, in image 3 In the directions shown, rubbing treatment was applied to the first and second alignment films so as to give liquid crystal molecules a certain Brewster angle in the same direction as each other.
[0076] Facing the first and second alignment films, a spacer 5 manufactured by Sekisui Fine Chemicals (Co., Ltd.) was used to make the substrate interval 5.3 μm, and a Strat manufactured by Mitsui Topress Chemical Co., Ltd. was used. (Struck) Adhesive 352A is bonded together, and the liquid crystal cell 9 (liquid crystal cell M) is produced.
[0077] Then, a liquid crystal MJ96435 (refractive ind...
Embodiment 3
[0081] A liquid crystal cell N was produced in the same manner as in Example 2 except that the material of the alignment film was different.
[0082] On the entire transparent electrodes 2 and 7 formed on the two transparent substrates 1 and 8 made of glass, SiO was deposited laterally at an angle of 60° away from the normal direction of the substrates. Then, a vertical alignment agent lecithin was coated on the surface of the SiO film by a spin coating method, and dried in a 120° C. thermostat for 1 hour.
[0083] Facing the first and second alignment films, a spacer 5 manufactured by Sekisui Fine Chemicals (Co., Ltd.) was used to make the substrate interval 5.3 μm, and a Strat manufactured by Mitsui Topress Chemical Co., Ltd. was used. (Struck) Adhesive 352A is bonded together, and the liquid crystal cell 9 (liquid crystal cell N) is produced.
[0084] Next, a liquid crystal MJ96435 (refractive index anisotropy Δn=0.138) was injected into the above-mentioned liquid crystal ...
