Abstract:
1. A rear type projector comprising: a projection unit that projects projection light modulated according to an image formation; a screen projection surface to which the projection light is projected and a liquid crystal panel that forms the image information, wherein: an optic axis of the projection light being projected to the screen projection surface is slanted relative to a normal of the screen projection surface according to a shape of the screen projection surface; the projection unit is disposed behind the screen projection surface and a reflector reflects the projection light projected from the projection unit; the image information is converted into virtual image information having image distortion caused by a slanted projection subjected to correction processing; and the conversion to the virtual image information makes pixels on the liquid crystal panel narrower in width due to a range of a light oath of the projection light becoming longer corresponding to the slant towards a shorter range.
