ABSTRACT:
A liquid crystal display which can give mono-domain alignment of the ferroelectric liquid crystal without forming alignment defects. The liquid crystal display has a UV curable liquid crystal side substrate having a first substrate, an electrode layer formed on the first substrate, a first alignment layer formed on the electrode layer, and a UV curable liquid crystal layer with a UV curable liquid crystal fixed and formed on the first alignment layer; and a counter substrate having a second substrate, an electrode layer formed on the second substrate, and a second alignment layer formed on the electrode layer. The UV curable liquid crystal layer of the UV curable liquid crystal side substrate and the second alignment layer of the counter substrate are disposed so as to face each other such that a ferroelectric liquid crystal is sandwiched between the UV curable liquid crystal side substrate and the counter substrate.
