ABSTRACT:
A liquid crystal panel device, being able to transfer heat generation within each of cells building up a panel, into an outside thereof, effectively, therefore being suitable for use in a liquid crystal projection, etc., comprises: a TFT substrate30, which is formed with semiconductor portions24and pattern layers28in large numbers on the surface thereof; an opposed substrate29; and a liquid crystal layer27hermetically enclosed between them, wherein heat interruption layers31are formed on a surface of the opposed substrate, in opposite to the liquid crystal layer, at the same positions to those of the semiconductor portions, which are formed on the FTF substrate30, and further comprises an anti-dust glass plate23disposed at the light-inlet side thereof, so as to define a space, including a gap11and grooves32, for receiving a cooling liquid11therein, on the opposite side surface of the opposed substrate, in vicinity of the heat interruption layers, thereby achieving cooling, effectively, so as to obtain the liquid crystal panel device being long in the lifetime and high in reliability thereof.
