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 substrate, which is formed with semiconductor portionsand pattern layersin large numbers on the surface thereof; an opposed substrate; and a liquid crystal layerhermetically enclosed between them, wherein heat interruption layersare 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 substrate, and further comprises an anti-dust glass platedisposed at the light-inlet side thereof, so as to define a space, including a gapand grooves, for receiving a cooling liquidtherein, 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.
