ABSTRACT:
A liquid crystal display device comprises a pair of substrates each provided with a transparent electrode, and a ferroelectric liquid crystal disposed therebetween. One of the substrates has thereon a homogeneous alignment, and the other substrate has thereon a tilted alignment film for aligning liquid crystal molecules in contact therewith in a tilted direction with respect to the face thereof. The combination of the two-types of alignment films provides a monodomain of uniformly aligned ferroelectric liquid crystal molecules, which leads to an improved display characteristic including increased contrast.
