<P>PROBLEM TO BE SOLVED: To provide a projector for reducing the temperature difference within a surface of a liquid crystal panel, and efficiently cooling the liquid crystal panel. <P>SOLUTION: A projector includes: the liquid crystal panel 341 having liquid crystal encapsulated between a pair of substrates, and a liquid-cooling device adapted to cool the liquid crystal panel 341 with a cooling liquid. A first translucent substrate Cr1 made of an optical crystal material having thermal conductivity in a direction parallel to an optical axis OAx higher than thermal conductivity in a direction orthogonal to the optical axis is disposed on an outer surface of one of the pair of substrates. The liquid-cooling device includes a liquid circulation pipe 51 that has a pipe shape passing the cooling liquid and is disposed along side end sections CrL1, CrR1 and CrD1 in the first translucent substrate Cr1. The liquid circulation pipe 51 is coupled to the first translucent substrate Cr1 in a manner of enabling heat transfer so that flow directions R1 and R2 of the cooling liquid are orthogonal to the optical axis OAx. <P>COPYRIGHT: (C)2011,JPO&INPIT |
