ABSTRACT:
A display device for displaying an image has a light source; an image forming element array for forming images of irradiation light beams emitted from the light source; a display panel including two-dimensionally arrayed pixels defined as a unit for controlling an intensity of transmitted light beams; image displaying section which the transmitted light beams with the irradiation light beam intensity controlled; and a light distributing section for splitting and distributing the irradiation light beams to said image forming element array, disposed between the light source and the image forming element array. The light distributing section is realized by either one of a lens array consisting of a plurality of lenses, which splits the irradiation light beams according to the plurality of lenses and converges the split light beams or an ellipse mirror constructed of two or more different rotary elliptical surfaces. This display device can be applied to a projection type display device by adding a projecting section which projects the light beams emerging from the display panel upon a screen or a pupil.
