Abstract
A liquid crystal display having a wide color reproduction range is provided. A liquid crystal display includes a liquid crystal panel driven based on image signals, a light source emitting light for illuminating the liquid crystal panel, and a light selective transmission filter, which has wavelength selective transmission characteristics corresponding to spectral characteristics of the light source, selectively transmits light generated from the light source in the specific wavelength regions based on the wavelength selective transmission characteristics, and guides the transmitted light to the liquid crystal panel.
