Abstract

There is provided a projection display device with a dummy glass (61), in which picture quality can be improved by reducing a visual pixel gap between an imaging element and a project lens (23). The projection display device includes a light source (2) for emitting a light, an imaging element (35) for forming an image by using the light and an input image signal, a projection lens (23) for enlarging and projection the image on a screen, and an angle shifter (21, 22) disposed between the imagining element (23) and the screen. The angle of the light enlarged and projected on the screen. The angle, shifter (21, 22) includes an angle shifting, plate (61) to visually remove gaps between pixels to the imaging element.
