<P>PROBLEM TO BE SOLVED: To prevent occurrence of color unevenness at lighting of a lighting system for display device using light-emitting diodes as a light source. <P>SOLUTION: Two sets of light-emitting diodes 4 having three colors of different wavelength of red, green, and blue as one set are installed in a case 3, and a case 3 is attached to one of four corners of rectangle of a light guide plate 1. A reflecting plate 5 which reflects the light emitted from the light-emitting diodes 4 is installed in the case 3, and the reflecting plate 5 and the light-emitting diodes 4 are arranged in such a posture that when the light emitted from the light-emitting diodes 4 are reflected by the reflecting plate 5 and emitted to the outside of the case 3 and enter into the light guide plate 1, the light may be converged and enter into the center of the thickness of the light guide plate 1. <P>COPYRIGHT: (C)2007,JPO&INPIT |
