Patent ID: 8282260

Claim:
A display apparatus comprising: a display panel which displays an image; a light source which generates and emits light used by the display panel to display the image; and a plurality of light guiding plates each including: a light incident surface facing the light source, the light emitted from the light source being incident on the light incident surface; a counter surface disposed facing the light incident surface; a light emitting surface facing a rear surface of the display panel and disposed adjacent to the light incident surface, the light emitting surface including an ineffective light emitting area adjacent to the light incident surface and an effective light emitting area connecting the ineffective light emitting area with the counter surface; the rear surface of a first light guiding plate of the plurality of light guiding plates partially overlaps with the effective light emitting area of a second light guiding plate, and a light guiding plate array arranged along a first direction includes the first light guiding plate and the second light guiding plate disposed adjacent to each other and partially overlapped with an end portion of each, wherein a rear surface of the light guiding plate array further comprises; a first area corresponding to the effective light emitting area in which the LGPs overlap with each other excepting for the ineffective light emitting area, the first area being adjacent to the light incident surface, a light diffusion pattern being formed in the first area; a second area corresponding to the effective light emitting area in which the LGPs overlap with each other, the second area being adjacent to the counter surface, the light diffusion pattern being formed in the second area; and a third area connecting the first area with the second area, the light diffusion pattern being formed in the third area, density of the light diffusion pattern in the third area being higher than that in the first and second areas.
