Abstract:
1. A liquid crystal display device comprising: a liquid crystal display element including a liquid crystal layer, color filters, arranged for each of a plurality of subpixels obtained by pixel partitioning, said color filters each being configured to transmit a predetermined color wavelength by absorbing wavelengths other than said predetermined color wavelength, and transmissive aperture parts, provided on a substrate for each of said subpixels, and displaying an image by switching, with a voltage impressed on the liquid crystal layer, the quantity of light transmitted through said apertures; a backlight for illuminating said liquid crystal display element; color separation filters in which reflectance of light with wavelengths absorbed at said color filters is higher than reflectance of light with wavelengths transmitted through said color filters; light collecting elements collecting light from said backlight in said transmissive aperture parts; wherein said color separation filters are positioned between the color filters and the backlight and configured so that the light of the wavelength passed through said color filters is collected by the light collecting elements and the light of the wavelength absorbed at said color filters is reflected by said color separation filters toward the backlight, wherein each of the light collecting elements corresponds, in a direction of a section of each light collecting element having a curvature, to only one of the transmissive aperture parts.
