ABSTRACT:
The liquid crystal device has a pair of flat glass substrates, a pair of dielectric multilayer film mirror, a plurality of transparent electrodes arranged in a matrix, a plurality of minute insulating films formed on inner face of the glass substrates, and a liquid crystal layer. A pair of dielectric multilayer film mirror constitute a Fabry-Perot etalon via the liquid crystal layer and enhance a contrast ratio. The minute insulating films are formed by physical vapor deposition and attain a uniform thickness, so that a liquid crystal device having a uniform cell gap is obtained.
