摘要： A light source portion having laser light sources emitting red light, green light, and blue light and conventionally disposed integrally with the liquid crystal display panel is spatially separated from the liquid crystal display panel. Accordingly, the power supply, the optical system, and the heat source are incorporated into the light source portion and are thereby completely separated from the liquid crystal display panel. A laser beam emitted from the light source portion is guided to the liquid crystal display panel via a fiber. In this manner, it is possible to achieve a liquid crystal display device capable of significantly reducing the liquid crystal display panel in thickness and weight.

摘要： A laser projector includes a laser light source; a two-dimensional light modulator which modulates light from the laser light source; and a projection optical system which projects images onto a display plane by expanding the light modulated by the two-dimensional light modulator. Shift of a display position of the two-dimensional light modulation element and shift of the projection optical system are performed in synchronization with each other so that display positions of the images on the display plane are made substantially identical to each other. Thereby, speckle noise is sufficiently removed, and high-grade images are displayed.
