Patent ID: 6847425

Claim:
A liquid crystal display comprising: a liquid crystal cell comprising, a first transparent substrate, a second transparent substrate opposing the first transparent substrate and being at a light-incident side, a liquid crystal layer disposed between the first transparent substrate and the second transparent substrate, a first transparent electrode formed on an inner surface of the first transparent substrate, the inner surface opposing the second transparent substrate, a first alignment film formed on the first transparent electrode, a second transparent electrode formed on an inner surface of the second transparent substrate, the inner surface opposing the first transparent substrate, and a second alignment film formed on the second transparent electrode; a reflector attached on an outer surface of the first transparent substrate with a bonding layer therebetween; a first retarder disposed on an outer surface of the second transparent substrate; a second retarder disposed on the first retarder; and a polarizer disposed on the second retarder; wherein the reflector comprises a resin substrate having an irregular surface and a metal reflection film disposed on the irregular surface of the resin substrate, the surface of the metal reflection film also being irregular due to the irregular surface of the resin substrate, and the reflector is arranged so that the metal reflection film opposes the first transparent substrate, wherein the reflector further comprises a plurality of concavities that reflect light formed in the surface of the reflector, each of the plurality of concavities having a first vertical cross-section and a second vertical cross-section that pass through the deepest point of the concavity, wherein the first vertical cross-section, showing a shape of the inner surface of the concavity, has a first curved line from an edge of the concavity to the deepest point and a second curved line from the deepest point of the concavity to another edge of the concavity, and an average absolute value of tilt angles of the first curved line with respect to the surface of the reflector is larger than that of the second curved line, and wherein the second vertical cross-section is orthogonal to the first vertical cross-section, shows another shape of the inner surface of the concavity, and has a gentle curved line and two sharp curved lines extending from the two ends of the gentle curved line, the two sharp curved lines having a radius of curvature smaller than that of the gentle curved line.
