ABSTRACT:
In a rear projection type projector device, a transparent plate-like member is supported so as to incline from a vertical surface, and a lenticular screen and a Fresnel lens are placed on the transparent plate-like member. Accordingly, the lenticular lens and the Fresnel lens are in tight contact with the front plate owing to their own weight, and this makes it unlikely to create spaces between these components.
