<P>PROBLEM TO BE SOLVED: To easily thin a device. <P>SOLUTION: A red light emitting diode 51, a green light emitting diode 52, a blue light emitting diode 53 emit red light, green light, and blue light respectively. In the red light guide 61, a disposition end part 71 forming at least one of the end parts has a thickness sufficient for disposing the red light emitting diode 51, portions other than the disposition end part 71 have a thickness thinner than the disposition end part 7 and is formed in an almost flat plate shape, and the red light emitting diode 51 is disposed in the disposition end part 71. A green light guide part 62 and a blue light guide part 63 are similarly formed. The red light guide 61, the green light guide 62, and the blue light guide 63 are laminated so that the respective disposition end parts 71-73 are not overlapped. The red light guide 61 emits red light in the laminating direction. The green light guide 62 and the blue light guide 63 do the same. This invention can be applied to a color transmitting type liquid crystal display device for example. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
