ABSTRACT:
A reflection liquid crystal display is such that a transparent substrate is opposed to the first substrate with a liquid crystal layer placed therebetween, and the transparent substrate is disposed forward to the first substrate in the light-incident direction. A quarter-wavelength plate is disposed in the transparent substrate, and a polarization plate is disposed on the surface at the forward side thereof in the light-incident direction. And, a reflection layer besides acting as a color filter consisting of a cholesteric liquid crystal is disposed inside liquid crystal cells of the first substrate. In the case of a wide field-of-view angle, a scattering film is disposed forward to the polarization plate in the light-incident direction.
