Abstract
A structure of a color filter plate for a liquid crystal display panel is described. The structure includes a body having four truncated edges and two recessed portions. The four truncated edges are non-right-angled in shape and respectively formed at four vertexes of the body. The two recessed portions are respectively formed on two opposite sides of the body. When forming a color filter layer composed of plural color filter plates in delta arrangement, the overlapping area of three adjacent color filter plates can be lowered. The light leakage problem of the liquid crystal display panel is suppressed, and the picture quality and the contrast thereof are enhanced.
