摘要： An image display apparatus includes a backlight unit including a plurality of light sources arranged in a flat, a reflecting portion for reflecting light from the light sources, a diffuser for diffusing the light from the light sources and the light reflected from the reflecting portion, and a chassis for maintaining or supporting the light sources, the reflecting portion and the diffuser; and a liquid crystal display unit which receives the light diffused by the diffuser of the backlight unit. Concave portions are formed in the chassis at positions corresponding to electrodes of the plurality of light sources, positions corresponding to light-emitting portions of the light sources are arranged in a flat, and a circuit for driving the liquid crystal display unit is provided on a rear surface of a planar portion of the chassis. Accordingly, it is possible to realize a thin lightweight backlight with high luminance and high luminance uniformity.

摘要： A projector using coherent light as a light source includes: one or more coherent light sources emitting coherent light beams; a beam scanner which changes a direction of the coherent light beam; and a beam splitter which splits a beam into multiple segments and changes a phase of light of each split segment, the beam splitter being located in an optical path between the beam scanner and the coherent light source. This projector reduces speckle noises. The beam splitter includes a pair of transparent substrates; a plurality of parallel electrodes disposed on each surface of the pair of transparent substrates, the pair of the parallel electrodes being disposed in a perpendicular direction to each other. Voltages are applied to the respective electrodes at predetermined time intervals so as to produce different potentials in a liquid crystal sandwiched by the transparent substrates.
