Patent ID: 8593393

Claim:
A display apparatus comprising: a video receiver which receives a video signal; a video processor which processes the video signal received by the video receiver; a display panel which is divided into a plurality of display areas; a plurality of light guide plates which transmit light to the plurality of display areas of the display panel; a plurality of light source modules alternately arranged with and interposed between the plurality of light guide plates, each light source module being disposed along a lateral side of an adjacent light guide plate of the plurality of light guide plates and comprising a plurality of light sources for emitting light to the lateral side of the adjacent light guide plate, and a module substrate on which the plurality of light sources are mounted and which is disposed at a rear side of the adjacent light guide plate, the rear side of the adjacent light guide plate being perpendicular to the lateral side of the adjacent light guide plate; and a plurality of reflective plates which are respectively disposed on rear surfaces of the plurality of the light guide plates, and reflect the light emitted by the plurality of light sources and transmitted by the plurality of light guide plates toward the plurality of display areas, wherein each of the plurality of reflective plates is interposed between a rear surface of a corresponding light guide plate of the plurality of light guide plates and at least one module substrate of the plurality of module substrates, wherein the rear surface of the corresponding light guide plate faces the rear side, wherein at least one of the plurality of light guide plates comprises a first region disposed inside a light emission range of the plurality of light sources of a corresponding light source module of the plurality of light source modules, and a second region disposed outside the light emission range of the plurality of light sources of the corresponding light source module, and wherein a density of a second light guiding pattern formed in the second region is greater than a density of a first light guiding pattern formed in the first region, and the first light guiding pattern and the second light guiding pattern are alternately disposed in direction of which the light sources of the corresponding light source module are disposed.
