ABSTRACT:
A liquid crystal cell is formed by bonding a first substrate on which a first electrode and a first aligning film are formed, and a second substrate on which a second electrode and a second aligning film are formed by a seal member. A liquid crystal is filled in the liquid crystal cell. The thicknesses of the aligning films are set to 10 nm to 35 nm. An aligning treatment is performed twice on each of the aligning films in the opposite directions. The first aligning treatment is performed to give a pretilt angle of 5 degrees to the liquid crystal, and the second aligning treatment is performed to give a pretilt angle of 6 degrees to the liquid crystal, with the result that a pretilt angle of 1 degree is actually given to the liquid crystal. The glass-transition temperatures of the aligning films are selected to be about 250.degree. C., so that the aligning films are not transformed at the time of baking the seal member.
