Abstract
The invention provides a color liquid crystal display including (a) two transparent substrates A and B disposed in facing relation, (b) a plurality of switching elements disposed on a surface of the substrate A, the surface facing the substrate B, said switching elements defining an area, (c) a light-impermeable layer disposed on a surface of the substrate B, the surface facing the substrate A, and (d) a colored layer overlying the light-impermeable layer and defining a display area corresponding to the area defined by the switching elements. The colored layer has an extension extending over the display area in longitudinal and transverse directions of the display area. The extensions of the colored layer cover the light-impermeable layer therewith to thereby prevent a light reflected from the light-impermeable layer from entering the switching element. Thus, it is possible to prevent the black level of the display area from being whitened.
