One or more embodiments of a backlight assembly include a light guide plate (LGP), a light source module and an optical sheet. The LGP includes a side surface and an upper surface. The light source module includes a power-transmitting member and a plurality of point light sources disposed on the power-transmitting member. A side portion of the power-transmitting member is disposed on a peripheral portion of the upper surface adjacent to the side surface and a light-exiting surface of the point light sources facing the side surface to be adjacent to the side surface. The optical sheet is disposed on the upper surface. A portion of the optical sheet is disposed between a corner portion of the upper surface and the power-transmitting member adjacent to the light-exiting surface. The amount of the light absorbed by a reflective member may be decreased to improve the efficiency of the light.

A printed circuit board (PCB) includes a base substrate, an electrical wiring, a dummy pad and a thermally conductive adhesion member. The base substrate includes a light-emitting diode (LED) mounted on a first surface of the base substrate. The electrical wiring is electrically connected to the LED. The dummy pad is formed on the first surface to be connected to the electrical wiring. The thermally conductive adhesion member is attached to a second surface of the base substrate. Therefore, superior heat radiation may be obtained, thereby reducing or preventing damage to the LED and the LCD device using the LED by radiating the heat from the LED used as a light source.

A backlight assembly includes a light source, a light-guide plate, a mold frame and a bottom chassis. The mold frame includes a first bottom portion, a protrusion on a first surface of the first bottom portion and a first sidewall portion on a second surface of the first bottom portion opposite to the first surface of the first bottom portion and facing the light guide plate. The bottom chassis includes a second bottom portion having a hole to receive the protrusion of the first bottom portion, and a second sidewall portion facing the light guide plate. A cross sectional area of a first opening of the hole corresponding to an inner surface of the bottom chassis and contacting the first surface of mold frame is different than a cross sectional area of a second opening of the hole corresponding to an outer surface of the bottom chassis.

An apparatus for dual display includes a light unit providing a light and a display panel. The display panel includes a transmissive pixel transmitting the light from the light unit and a reflective pixel reflecting the light from the light unit. The display panel displays a first image on one side of the light unit by using the light transmitted by the transmissive pixel, and displays a second image on an opposite side of the light unit by using the light reflected by the reflective pixel. The display panel includes a first substrate, a second substrate combined with the first substrate and disposed adjacent to the light unit, and a liquid crystal layer interposed between the first and the second substrates. The display panel further includes a reflective layer formed on the first substrate corresponding to the reflective pixel. Therefore, a total thickness of the apparatus for dual display can be reduced considerably by using the light unit as a second display screen.

Disclosed is a liquid crystal display apparatus in which a liquid crystal display module and cases are tightly combined. At least one protuberance formed on a top chassis of the liquid crystal display module combines at least one fixing portion formed on a portion of a rear case corresponding to the at least one protuberance. Also, a fixing protuberance formed on a portion of a front case is inserted into between the liquid crystal display module and the rear case, thereby preventing the liquid crystal display module from being moved. Therefore, the liquid crystal display module and the cases are tightly combined, and productivity of the liquid crystal display apparatus can increase by reducing the number of parts demanded for fabrication of the liquid crystal display module and the cases.

Liquid crystal display apparatus having particular fixing grooves and fixing protuberances in rear case

Disclosed is a liquid crystal display module having a reduced thickness thereof. A light exit surface of a light guiding plate for converting a linear light source output from the lamp in the form of planar light source is non-planarized with a plurality of convex portions having a desired height. A prism sheet for controlling a path of the light output from the light guiding plate is laid on the light guiding plate, as being opposite the plurality of convex portions. Accordingly, it is possible to uniformly control the brightness distribution of the light output from the light guiding plate without providing a separate diffusing plate between the light guiding plate and the prism sheet. In addition, since the plurality of convex portions which are formed integrally with the light guiding plate directly faces the prism sheet, adherence between the light guiding plate and the prism sheet can be prevented. Therefore, the diffusing plate can be eliminated from the liquid crystal display module, thereby reducing the number of components, and thus minimizing the thickness of the liquid crystal display module.
