Abstract:
A ferroelectric liquid crystal display comprising:a pair of first and second substrates placed substantially in parallel to each other to form a space between said first and second substrates; a first orientation film extending over an inner surface of said first substrate so that said first orientation film faces said space; a second orientation film extending over an inner surface of said second substrate so that said second orientation film faces said space; and a ferroelectric liquid crystal provided in said space between said first and second orientation films, wherein an entirety of said first orientation film is unidirectionally oriented to have a first orientation direction and an entirety of said second orientation film is unidirectionally oriented to have a second orientation direction which differs from said first orientation direction by an angle of 90 degrees+2&agr;, where &agr; is an angle by which an optical axis of said ferroelectric liquid crystal differs in a clockwise direction from a unidirectional orientation direction of one of said first and second orientation films when the remaining one of said first and second orientation films is not oriented, and wherein said ferroelectric liquid crystal is isolated into co-existent different two types of local areas which differ by 90 degrees from each other in initial orientation direction toward which an optical axis of ferroelectric liquid crystal molecules is directed under no electric field applied to said ferroelectric liquid crystal immediately after said ferroelectric liquid crystal has been injected into said space between said first and second substrates.
