Abstract:
A liquid crystal display, using a ferroelectric liquid crystal exhibiting mono-stability, which makes it possible to control the direction of the spontaneous polarization of the ferroelectric liquid crystal. The liquid crystal display includes: a first alignment treatment substrate having a first alignment layer which is a rubbed layer; a second alignment treatment substrate having a second alignment layer which is a photo alignment layer using a photo-dimerization type material; and a liquid crystal layer containing a ferroelectric liquid crystal and held between the first alignment treatment substrate and the second alignment treatment substrate. The ferroelectric liquid crystal exhibits mono-stability, and when a negative voltage is applied to a second electrode layer of the second alignment treatment substrate, a molecular direction of the ferroelectric liquid crystal is changed by about 2 times a tilt angle of the ferroelectric liquid crystal parallel to a surface of the substrate.
