ABSTRACT:
A projector for magnifying and projecting an image displayed on LCDs and illuminated by a light source through a projecting lens is designed so that the adherence of dust to the LCDs and the rise of the temperature of the LCDs is suppressed. The peripheral portions of the LCDs are supported by supporting frames. And, the LCDs are hermetically held by a front side glass and a rear side glass which are closely mounted to the peripheral portions of the supporting frames with an adhesive.
