Abstract:
1. A liquid crystal display device comprising: two substrates arranged so as to be opposed to each other; parallel flat electrodes formed on the surfaces of the two substrates and at least one of which is a transparent electrode and at least one of which is a pixel electrode; and a liquid crystal layer having liquid crystal sandwiched between the parallel flat electrodes, wherein one pixel is made up of two or more sub-pixels controllable independently of each another, wherein the area of a display effective domain of at least one of the two or more sub-pixels is different from the area of the display effective domain of other sub-pixels, wherein the display effective domain of each sub-pixel is defined by the domain of a wavelength selection layer, wherein the sub-pixels are separated from one another by a black matrix such that the wavelength selection layers of each sub-pixel do not contact one another, and wherein the wavelength selection layer is a color filter formed by mixing transparent resin with pigment or dye, and wherein a desired chromaticity is obtained by varying a thickness of the color filter without varying the amount of pigment or dye in the color filter.
