摘要： A backlight unit 12 includes light guide members 18. Each light guide member 18 is configured such that a maximum amount of light exits an area of a light exit portion 31 located more to the front end than the middle of an area between an end of the light exit portion located adjacent to a light guide portion 32 and the front end of the light exit portion 31 when a distribution of the amount of outgoing light is measured. With this configuration, a uniformity of in-plane brightness can be further improved.

摘要： An LCD device using LEDs as light sources provided herein is capable of reducing the manufacturing cost and the power consumption by a reduction in the number of LEDs used. A backlight according to the present invention includes LEDs mounted on a wiring board and a light guide plate having a matrix array of light guide plate blocks assigned the LEDs. The number of LEDs assigned to the block located in a peripheral area is smaller than the number assigned to the block located around the center to reduce the number of LEDs used in the backlight. If a ratio of the brightness in a peripheral area of the screen to the brightness in a central area is 60% or higher, the human eye does not perceive non-uniform luminance. Thus, the manufacturing cost and the power consumption of the LCD device can be reduced.
