PURPOSE:To uniformly orient a ferroelectric liq. crystal by using a cyanoethylcellulose film as at least one of oriented films. CONSTITUTION:A transparent electrode and an oriented film are successively formed on each of two substrates, the substrates are arranged with the oriented films inward, and a liq. crystal, preferably a ferroelectric liq. crystal is sealed in the space between the films. At this time, at least one of the oriented films is made of cyanoethylcellulose. The cyanoethylcellulose oriented film may be formed on the transparent electrode by dissolving cyanoethylcellulose in a solvent such as 2-methylpyrrolidone and applying the resulting soln. with a spin coater. It is preferable that the oriented films are slightly rubbed with nylon or the like. Thus, the liq. crystal is uniformly oriented and a bistable liq. crystal display device is obtd. |
