<P>PROBLEM TO BE SOLVED: To provide a device without making it large-sized, and also, with high luminance, high proportion, and little color unevenness, as well as with high display quality. <P>SOLUTION: With a backlight unit 1, light is emitted from a blue-color LED 5B, a green-color LED 5G, and red-color LED 5R. Here, the red-color LED 5R is a light-emitting element of an inverted pyramid shape, with excellent emission efficiency. For that, there is a fear of stray light generated as the light is reflected at a wiring board 6 and a wall face of the magazine 15 of a collimator lens 9. Such stray light is absorbed by a light-absorbing part 16 formed at each wall face forming the magazine 15 of the collimator lens 9 to have red-color stray light prevented from getting intense, and moreover, emitted light from the blue-color LED 5B and the green-color LED 5G is increased by the collimator lens 9 at a light-emitting face member 4 in the vicinity of the light source part where emitted light from the red-color LED 5R has been relatively prevalent, so that color unevenness is surely restrained. <P>COPYRIGHT: (C)2009,JPO&INPIT |
