Patent ID: 7654692

Claim:
A spread illuminating apparatus of a liquid crystal display device, the spread illuminating apparatus comprising: a driving circuit having a control section adapted to control a plurality of lighting units by selectively and independently turning each lighting unit on or off; and a plurality of edge light type lighting units arranged two dimensionally in a matrix, each lighting unit comprising: a light conductor plate having one major surface as a light emitting surface, two or more light emitting diodes disposed at one side of the light conductor plate, the light emitting diodes including at least one pseudo white light emitting diode, and a circuit substrate on which the light conductor plate and the light emitting diodes are mounted, the circuit substrate being connected to the driving circuit, wherein light, emitted from the light emitting diodes and introduced into the light conductor plate, exits from the one major surface in a uniform manner through the light conductor plate, wherein each of the lighting units further comprises an angle adjusting means to adjust an inclination angle of light emitting surface of the light conductor plate with respect to the liquid crystal display device.
