<P>PROBLEM TO BE SOLVED: To eliminate color unevenness by shortening a region for color mixing and surely performing color mixing. <P>SOLUTION: LED packages 1, 2, ..., 9 are arrayed in a parallel row at an interval S along a light-incident end face T1 of a light guide plate 10. Each LED package 1, 2, ..., 9 is provided with a red LED chip R, a green LED chip G, and a blue LED chip B. A length direction of a light-emitting face of each LED package 1, 2, ..., 9 and the light-incident end face T1 are set vertical to each other. Red-color light, green-color light and blue-color light from the red LED chip R, the green LED chip G and the blue LED chip B of each LED package 1, 2, ..., 9 are mixed before they reach the light-incident end face T1 of the light guide plate 10, that is, color unevenness is eliminated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
