PURPOSE: To obtain a wide visual field angle and high-speed responsiveness, to make it possible to display gradation and to improve an opening rate by combining a monostable ferroelectric liquid crystal element (monostable FLC element) and active matrix elements such as TFTs for driving this FLC element. CONSTITUTION: An N-methyl-2-pyrrolidone soln. is applied on the TFT 6 side of a glass substrate 1a and is baked to form a polyimide oriented film 5a. This film is subjected to an orientation treatment by rubbing. A common electrode 4 side is formed with a black matrix 2 of chromium, color filters 3 and transparent electrodes (ITO) 4 on a glass substrate 1b and is formed with a polyimide film 5b on the surface of the ITO. This film is subjected to the orientation treatment by rubbing. The TFT side panel and the color filter side panel are so combined that the orientation treatment directions are counter-paralleled on the opposite surfaces. The gap between the substrates is controlled by using spacers 7 and the circumference of the cell is adhered with a sealant by assuring the injection hole for liquid crystals. The injection hole is then sealed with a UV curing adhesive, by which the monostable FLC element is obtd.
