Patent ID: 7136137

Claim:
A liquid crystal panel device, comprising: a substrate formed with semiconductor portions and pattern layers in plural numbers on a surface thereof; an opposed substrate disposed in opposite to said substrate upon a surface thereof, on which the semiconductor portions and the pattern layers are formed; and a layer of liquid crystal enclosed between said substrate and said opposed substrate, whereby forming liquid crystal cells in plural number within an inside thereof, further comprising: a heat interruption layer being formed on a surface of said opposed substrate in opposite to said liquid crystal layer, corresponding to the semiconductor portions formed on said substrate; a transparent plate being provided in opposite to said opposed substrate, at an upstream side of an optical path of an incident light upon said device; and further a space for receiving a cooling medium within an inside thereof, upon a surface of said opposed substrate, being opposite to the side on which said heat interruption layer is formed, and in vicinity of said heat interruption layer; wherein said cooling medium is received within grooves formed on a surface of said opposed substrate, facing to said transparent plate disposed in opposition thereto, at the upstream side of the optical path of the incident light; and wherein said grooves are formed vertically or/and horizontally along with said heat interruption layers, on the surface of said opposed substrate.
