Patent ID: 8130358

Claim:
A liquid crystal display comprising: a first alignment treatment substrate having a first substrate, a first electrode layer formed on the first substrate, and a first alignment layer which is formed on the first electrode layer and which is a rubbed layer; and a second alignment treatment substrate having a second substrate, a second electrode layer formed on the second substrate, a second alignment layer which is formed on the second electrode layer and which is a photo alignment layer using a photo-dimerization type material to exhibit anisotropy to an alignment layer by generating a photo-dimerization reaction; and a ferroelectric liquid crystal held between the first alignment layer of the first alignment treatment substrate and the second alignment layer of the second alignment treatment substrate; in which the first alignment layer of the first alignment treatment substrate and the second alignment layer of the second alignment treatment substrate are provided to face each other, wherein the ferroelectric liquid crystal exhibits mono-stability, and further wherein, when a negative voltage is applied to the second electrode layer, 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 first alignment treatment substrate.
