Abstract
A color liquid crystal display for improving the white balance of the color filter by using a multilayer structure of inorganic thin films and preventing a liquid crystal cell from being colored is provided. The spectral transmission characteristic is such that the transmission wavelength area of the G (green) filter is narrowed. For the pixel array having four pixels as a constituent, two pixels for the G filter are arranged diagonally and the remaining two pixels consist of R (red) and B (blue).
