    摘要: A side-light type backlight includes a light source having a plurality of LEDs and a light guide plate, where opposing end surfaces of the light guide plate define light incidence surfaces, with the plurality of LEDs being arranged at one of the light incidence surfaces. A number, M, of the LEDs are arranged in a longitudinal direction of the light incidence surface of the light guide plate, and are electrically connected such that there are a plurality of groups of the LEDs with each group having N LEDs mutually adjacently arranged in series. The groups are adjacently arranged in a longitudinal line, and at least one of the groups of LEDs is a separate parallel connection from an adjacent group of LEDs. The plurality of LEDs includes LEDs having a plurality of colors, and the LEDs arranged in series include LEDs having different colors.

    摘要: A backlight unit has a light source, a reflection sheet, a light guide plate, an air space, and a diffuser, wherein the reflection sheet, the light guide plate, the air space, and the diffuser are overlaid in this order. The light source is configured to arrange individual light sources having different spectra or different light emission quantities near an incident plane of the light guide plate, and on a plane facing the reflection sheet of the light guide plate, scatter dots are disposed which take light propagating through the light guide plate out of the reflection sheet side. The backlight unit and a liquid crystal display device including the same have excellent display quality.

    摘要: A liquid crystal display device includes: a liquid crystal spatial modulating element holding a liquid crystal layer between a pair of parallel substrates, wherein transmission of light incident upon the liquid crystal layer along an incidence direction tilted to a predetermined direction from a normal to the substrates takes a local minimum as a voltage applied to the liquid crystal layer is changed, and the voltage at the local minimum changes as the incidence direction is changed; an illumination optical system for supplying illumination light generally over a whole surface of the liquid crystal spatial modulating element along incidence direction or directions tilted to the predetermined direction; and a driver circuit capable of applying a voltage across the liquid crystal layer, the voltage being generally equal to a voltage which provides the local minimum of the transmission with respect to the illumination light. The liquid crystal display device has uniform display characteristics over a display screen.

    摘要: A light source for use in a projection type liquid crystal display device. The light source includes an electrodeless light emitting member having a light emitting material sealed in a transparent tube to emit light upon the application of microwave electromagnetic energy. A concave mirror is arranged on the outside of the light emitting member, and the transparent tube is supported by a rotatable rod-like support member which extends through the concave mirror. Means in the form of a vane, a screw or a projection is arranged on the rod-like support member or on the light emitting member for stirring air, while the rod-like support member rotates, to cool the light emitting member.
