  • Patent number: 7804551
    Abstract: A liquid crystal display (LCD) panel including a color filter substrate, a liquid crystal layer and a semiconductor array substrate is provided. The liquid crystal layer is disposed between the two substrates. The semiconductor array substrate disposed at one side of the color filter substrate includes a transparent base, a planar layer, several pixel electrodes and an opaque layer. The pixel electrodes are arranged in an array on the planar layer, which covers the transparent base. Each two adjacent pixel electrodes are spaced by a gap. The opaque layer is disposed in the planar layer, and is located beneath each gap. The opaque layer having an extended portion disposed at two sides thereof is extended towards two sides of each gap to be under part of the pixel electrodes. The opaque layer is at least a half of the planar layer in thickness.
