Abstract
To provide a display device and a projector capable of enhancing the quality of dynamic images, of reducing limitations on light sources, enhancing the utilization efficiency of light, and of displaying images in full color, illumination light emitted from a light source lamp is irradiated onto some pixels of a liquid crystal light valve capable of displaying images in colors. A rotating prism scans the illumination light. At this time, fly eye lenses and an superposing lens condense illumination light emitted from the light source lamp to form an image. The image formed by the fly eye lenses and the superposing lens is formed again on the liquid crystal light valve by the image re-forming lenses. The image of the liquid crystal light valve is enlarged and projected by the projection lens to a screen.
Claims9
A display device, comprising:
- a light source to emit illumination light;
- a display element having a plurality of pixels to modulate the illumination light;
- an irradiation optical system to irradiate the illumination light emitted from the light source onto some of the pixels;
- and
- an illumination light scanning device to scan the illumination light irradiated by the irradiation optical system,
- the irradiation optical system including an image forming device to condense the illumination light emitted by the light source to form an image and image re-forming device to form the image formed by the image forming device on the display element, and
- the illumination light irradiated onto the display element being irradiated onto the display element by at least the image forming device and the image re-forming device.
