ABSTRACT:
A projection-type display device comprises a pillar optical element having an injection end and an emitting end, a lamp, an elliptical mirror for condensing light emitted by the lamp in the vicinity of the injection end, a first lens for forming an image of the emitting end, a light valve for forming a picture image on a surface having an image display area, and a projection lens. The image of the emitting end of the pillar optical element is projected by the first lens on the image display area within the surface of the light valve. The projection lens magnifies and projects the picture image displayed by the light valve on the screen.
