Abstract: There is provided a slim liquid crystal display unit having a large screen by providing a slim structure capable of sufficiently radiating the heat from a light source. The liquid crystal display unit according to the present invention includes: a liquid crystal panel; an optical guiding board installed on a rear face thereof; a pair of light source-mounted substrate disposed, opposing right and left side faces thereof; a light source mounted on the light source-mounted substrate; a metal frame connected on the opposite side to the optical guiding board of the light source-mounted substrate; a chassis member for supporting the optical guiding board and a reflection sheet group; and a thermal diffusion member fixed onto the metal frame along with the chassis member. The chassis member has a stepped portion in the vicinity of the light source. Between the stepped portion and the reflection sheet group, a thermal insulation member is attached.

Abstract: 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.

Abstract: The invention makes patterns which may show, according to the positioning of light guide plates, along the vertical direction of a display screen of a side-edge type liquid crystal display device inconspicuous. This is achieved by disposing light guide plates so as to guide the illumination light from light sources, for example, LEDs along the vertical direction of the display screen. The vertically guided illumination light is reflected, with reflection sheets also facilitating the reflection, at rear sides of the light guide plates and is, after traveling through a diffusion sheet to be made more uniform, further guided to liquid crystals. Even though boundaries between light guide plates are generally more conspicuous along the vertical direction of a display screen than along the horizontal direction, first guiding the illumination light into a vertical direction removes the problem of such boundaries conspicuously showing along the vertical direction.

Abstract: A liquid crystal display device is provided in which, even when divided light guide plate blocks are thermally expanded or contracted as a result of a temperature change, the generation of clearances and mechanical deformations between such divided light guide plate blocks is prevented, making it possible to reduce the brightness unevenness of the liquid crystal display device. To realize the above feature, light guide plate blocks are arranged such that one or two of them are arranged in each horizontal row with only an upper side of each light guide plate block fixed to a chassis and, furthermore, such that the upper side fixed to the chassis of each light guide plate block is based on a center in the horizontal direction of the liquid crystal display panel so as to reduce the effects of thermal expansion and contraction of each light guide plate block.
