Patent ID: 7643109

Claim:
A color filter substrate comprising: a substrate having a first surface and an opposed second surface; and at least a black matrix layer, a color filter layer, and a retardation layer stacked on the first surface of the substrate; wherein the black matrix layer and the color filter layer are stacked on the first surface of the substrate while providing a margin around the periphery of the first surface of the substrate; wherein the retardation layer is stacked with the black matrix layer and the color filter layer in a larger area than an area where the black matrix layer and the color filter layer are stacked; wherein the margin around the periphery of the first surface of the substrate, where neither the black matrix layer nor the color filter layer are stacked, defines an area to be sealed; wherein the color filter substrate is used for a liquid crystal display panel which comprises the color filter substrate and a counter substrate stacked on top of each other through a seal material, and a liquid crystal hermetically sealed between the substrates; wherein the retardation layer is located between the first surface of the substrate of the color filter substrate and the counter substrate in the liquid crystal display panel; and wherein the seal material is provided on at least pail of the retardation layer and the seal material does not contact the black matrix layer or the color filter layer.
