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.

Abstract: Light exposure areas 103 and light masking areas 104 in a sole reticle are arrayed in alternation to one another in both the longitudinal and transverse directions. Substrate is exposed to light by multi-domain light exposure using this reticle so that the respective areas of the reticle exposed to light with respective shots A to B, B to C . . . , N to M are not adjacent to one another in the boundary portions of the reticle shifted for executing the respective shots, thus relaxing the difference in illuminance between the respective shots and the difference in finish of the boundary portions of the shots, such differences becoming imperceptible to human eyes upon displaying liquid crystal display apparatus.
