摘要： A cross section of each divided light guiding plate is formed in a wedge shape, a step is formed at a portion of each divided light guiding plate where LEDs are arranged, and holes used for accommodating the LEDs are formed at the step. A plated face is formed on a lower face of each LED, and is coupled to a wiring substrate through solder. Each LED includes a light-emitting face, a lower frame, and an upper frame. The height of the lower frame of each LED is larger than the height of the upper frame, so that a lower end of the light-emitting face of each LED can be always located higher than a lower end of the divided light guiding plate.

摘要： In a liquid crystal display device, two light guide plates are arranged in parallel at a predetermined distance from each other to function as a backlight. The two light guide plates are provided between a liquid crystal display panel and a circuit substrate on which LEDs are mounted. Each of the light guide plates includes a plurality of divided light guide plates. Each of the divided light guide plates is divided into a plurality of light guide plate blocks by grooves. In opposed portions of the two light guide plates, side surfaces of the light guide plates are inclined. Then, a rough surface is formed on the respective inclined surfaces. Because of this shape, light interference easily occurs between the two light guide plates. As a result, it is possible to prevent lowering of brightness in the opposed portions of the two light guide plates.
