Abstract:
1. A liquid crystal display device, comprising: a light source; a light guide plate for causing light from the light source to enter from a side surface and exit as illuminating light from one principal surface; a liquid crystal panel which includes a reflective color filter having wavelength selectivity in transmittance and reflectance and a polarizing plate disposed on a side closer to the light guide plate than the reflective color filter, and which is disposed on a light path of the illuminating light; a recycle part for reflecting the illuminating light reflected with the reflective color filter toward the reflective color filter once again, and a polarization element for improving an extinction ratio of light entering the light guide plate in a light path between the light source and the light guide plate, wherein the light from the light source is configured to enter the light guide plate as approximately linear polarization, and the polarizing plate of the liquid crystal panel is configured to exhibit transmittance of 90% or higher.
