摘要： An objective of the present invention is to enable making a liquid crystal display device thin, and to enable regional control of window brightness with power conservation. A backlight of a liquid crystal display device comprises a plate-shaped light guiding plate (20). Recesses (21) are formed on the light guiding plate (20), and LEDs (30) are housed in the recesses (21). The LEDs (30) further comprise light emitting faces (301) and rear faces. The rear faces of the LEDs (30) are brought into contact with the interior walls of the recesses (21) of the light guiding plate, and light that leaks from the rear faces of the LEDs (30) is proactively used. A resin (25) for optical coupling is positioned between the LEDs (30) and the interior faces of the recesses (21). Using the light from the rear faces of the LEDs (30) allows reducing the number of LEDs that need to be lit, allowing obtaining a liquid crystal display device with minimized power consumption.

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： 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.

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.

摘要： In a liquid crystal display device having a direct-lighting backlight using LEDs as a light source, the number of LEDs is reduced without causing unevenness in brightness. An LED is disposed under a cylindrical lens to be closer to one end of the lens than a middle part of the lens. Light emitted from the LED is outputted, as diffused light, upward from an end diffusion surface of the lens. A portion of the top surface of the lens makes up a total reflection surface to reflect light emitted from the LED and thereby cause the reflected light to head for the other end of the lens. Diffusion surfaces formed on the top surface and the bottom surface of the lens radiate diffused light upward of the lens, causing uniform light to be radiated from the whole top surface of the lens.
