Abstract:
1. A liquid crystal display device, comprising: a light source for emitting light of at least two different wavelengths; a light guide plate for emitting light from one principal surface, the light being incident on a side surface of the light guide plate from the light source; a reflective color filter arranged to intersect with an optical path of the light emerging from the principal surface and including at least two types of filter regions having different spectral characteristics, each type of filter region being operable to transmit light having a corresponding one of the at least two different wavelengths; a recycle portion arranged at a side of the light guide plate opposite to the reflective color filter; and a liquid crystal panel including a plurality of subpixels for respectively transmitting light having a corresponding one of the at least two different wavelengths, an outer glass substrate disposed at a side of the plurality of subpixels opposite to the light guide plate, and an inner glass substrate disposed between the plurality of subpixels and the light guide plate; wherein, out of the light incident on the light guide plate, light reflected by the reflective color filter is returned to the reflective color filter again by being reflected by the recycle portion via the light guide plate, and the subpixels of the liquid crystal panel and the filter regions of the reflective color filter are provided between the outer glass substrate and the inner glass substrate, and are arranged in such a manner that light separated by the reflective color filter is incident on specified subpixels.
