Abstract

PURPOSE:To improve the contrast of a display by sandwiching a nematic liquid crystal layer which has positive dielectric anisotropy and is perpendicularly oriented while no electric field is applied by substrates provided with the plural electrodes opposedly disposed in parallel with only the surface of one substrate. CONSTITUTION:A nematic liquid crystal layer 11 which has positive dielectric anisotropy and is perpendicularly oriented while not applied with any electric field is provided, and one transparent substrate 4 is provided with a pair of electrodes 5 wherein electrodes 5a, 5b of a comb shape are disposed mutually parallel. When voltage is applied to the electrodes 5a, 5b by closing a switch 7, the liquid crystal molecules 11a on another substrate 4 side remain perpendicularly oriented, and on the substrate 4 side having the electrodes 5a, 5b, the liquid crystal melecules 11b orient parallel. Therefore, while no electric field is applied, the incident natural light from the polarizing plates 8 provided in a manner as to intersect the axes of polarization mutually orthogonally on the outer side of the substrates appears dark as it is absorbed by polarizing plates 9, but when applied with electric field, the light from the plates 8 is elliptically polarized by the layer 11 and passes through the plates 9 and therefore the display is bright. In this way, the high contrast not only in the color display but also in the black and white display is obtained.
