ABSTRACT:
A liquid crystal displaying apparatus has a reflection-type liquid crystal display with vertical orientation-mode liquid crystals, to modulate linearly polarized light. Also provided is a polarization and diffracting section to convert read light beams obliquely incident thereto to the linearly polarized light, to allow the linearly polarized light to be incident to the liquid crystal display, allow first polarized light components of the linearly polarized light modulated by the liquid crystal display to pass therethrough, the first polarized light components vibrating in a first direction perpendicular to a second direction in which the linearly polarized light vibrates, and diffract second polarized light components of the linearly polarized light to a third direction from which the read light beams be incident to the liquid crystal display, the second polarized light components vibrating in the second direction. Further provided are a quarter wavelength plate to allow elliptically polarized light which includes the first polarized light components and a small quantity of the second polarized light components to pass therethrough when the liquid crystal display is active for modulation, and a polarizer to allow polarized light components of the elliptically polarized light to pass therethrough, the polarized light components matching a transmission axis of the polarizer.
