Patent ID: 8690409

Claim:
A backlight assembly comprising: a light guiding plate comprising: a light exiting surface through which light can exit; a light guiding surface opposite to the light exiting surface, the light guiding surface comprising a first incident portion and a second incident portion to receive the light respectively and a reflecting portion to reflect the light; a first side surface extending between the light guiding surface and the light exiting surface, the first side surface inclined with respect to the light guiding surface by a first acute angle; a second side surface opposite to the first side surface and extending between the light guiding surface and the light exiting surface, the second side surface inclined with respect to the light guiding surface by a second acute angle; a plurality of first light sources configured to generate the light toward the first incident portion, the first light sources being disposed only under the light guiding plate, and being disposed adjacent to a first edge connecting the first side surface of the light guiding plate with the light guiding surface; a plurality of second light sources configured to generate the light toward the second incident portion, the second light sources being disposed under the light guiding plate and disposed adjacent to a second edge connecting the second side surface with the light guiding surface; a first reflecting cover disposed on the first side surface and whose projected width onto the light guiding surface is larger than a width of the first incident portion; a second reflecting cover disposed on the second side surface and whose projected width onto the light guiding surface is larger than a width of the second incident portion; and a reflecting sheet disposed under the light guiding surface corresponding to the reflecting portion.
