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 30 , which is formed with semiconductor portions 24 and pattern layers 28 in large numbers on the surface thereof; an opposed substrate 29 ; and a liquid crystal layer 27 hermetically enclosed between them, wherein heat interruption layers 31 are 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 30 , and further comprises an anti-dust glass plate 23 disposed at the light-inlet side thereof, so as to define a space, including a gap 11 and grooves 32 , for receiving a cooling liquid 11 therein, 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.
