Patent ID: 8179504

Claim:
A liquid crystal display comprising: a liquid crystal panel driven based on image signals; a light source emitting light for illuminating the liquid crystal panel; and a light selective reflection filter, which has wavelength selective reflection characteristics corresponding to spectral characteristics of the light source, selectively reflects light generated from the light source in specific wavelength regions based on the wavelength selective reflection characteristics, and guides the reflected light to the liquid crystal panel, wherein the light source has respective intensity peaks at least in a red region, a green region, and a blue region, and wherein light reflectance of the light selective reflection filter has corresponding reflectivity peaks in the red region, the green region and the blue region, such that in wavelength regions of 460±10 nm, 535±10 nm and 660±10 nm the light reflectance of the light selective reflection filter is 80% or more for the corresponding reflectivity peaks, and the light reflectance in wavelength regions from about 475 to 510 nm and about 560 to 615 nm is 10% or less, to provide the selective reflection characteristics corresponding to spectral characteristics of the light source.
