ABSTRACT:
There is provided a projection display device with an angle shifter, in which the picture quality can be improved by reducing a visual pixel gap between an imaging element and a projection lens. The projection display device includes a light source for emitting a light, an imaging element for forming an image by using the light and an input image signal, a projection lens for enlarging and projecting the image on a screen, and the angle shifter disposed between the imaging element and the screen. The angle shifter periodically changes an incident angle of the light enlarged and projected on the screen. The angle shifter includes an angle shifting plate to visually remove gaps between the pixels of the imaging element.
