Abstract
In a rear projection type projector device, a transparent plate-like member (front plate) is supported so as to incline from a vertical surface, and a lenticular screen and a Fresnel lens are placed on the front plate. Accordingly, the lenticular lens and the Fresnel lens are in tight contact with the front plate owing to their own weights, and this makes it unlikely to create spaces between these components, whereby it is thus possible to prevent a decrease in resolution, the distortion of an image both associated with the creation of spaces, and the degradation of image quality.
Claims1
A rear projection type projector device comprising light image output means for outputting a light image, reflecting means for reflecting the light image from the light image output means, and a screen member on which the light image reflected by the reflecting means is projected, the device allowing the light image projected from a rear side of the screen member to be viewed from a front side of the screen member, the device further comprising:
- a transparent member located so as to incline from a vertical plane,
- wherein the screen member is located so as to be placed on the transparent member.
