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.

摘要： Each of plural light source units is formed by combining a light source formed of plural light emitting elements mounted on a wiring substrate with a light guide plate having a side surface serving as a light incident surface. The wiring substrate is attached to the chassis such that the light output surface of the light emitting element is perpendicular to the light emitting element mount surface of the wiring substrate. The wiring patterns each with the larger width than that of the electrode are formed on both upper and back surfaces of the substrate at the portion to which the power feeding electrode of the light emitting element is soldered. They are connected via the through holes which are arranged in plural rows around the electrode.

摘要： A liquid crystal display apparatus includes a backlight unit in which a diffusing member and an adjusting member are disposed on exit surfaces of light guide plates near a liquid crystal panel. The diffusing member diffuses light from the exit surfaces and the adjusting member adjusts the distribution of light from the exit surfaces. The light guide plate is as large as one of four equal parts of the liquid crystal panel as divided in vertical and horizontal directions.
