Liquid crystal display apparatus

摘要

Disclosed is an LCD apparatus having a reduced size and weight. The LCD apparatus includes a bottom chassis having a bottom surface and first to fourth sidewalls. The sidewall of the bottom chassis includes a supporting member for preventing a light guiding plate from being moved and a fixing boss for fixing an optical sheet. The bottom chassis includes a lamp insertion portion for receiving a lamp unit, which is disposed on the third and fourth sidewalls of the bottom chassis. The bottom chassis receives a reflecting plate, the light guiding plate and the optical sheet. A mold frame is coupled to the bottom chassis to fix the reflecting plate, the light guiding plate and the optical sheet to the bottom chassis. A display unit disposed on the mold frame is fixed to the mold frame by a top chassis coupled to the mold frame. Accordingly, a bottom mold frame for receiving a backlight assembly is removed, so that it is able to reduce a cost of the LCD apparatus and a weight thereof.

主权项

1. A backlight assembly comprising:
a light generating unit generating light; a light guide plate guiding the light, the light guide plate defining a first guiding portion, the first guiding portion defined by the light guide plate including a recess inwardly protruded with respect to a first side of the light guide plate; and a receiving container defining a bottom surface thereof which extends to define a plurality of sidewalls thereof, the bottom surface and the sidewalls defining a receiving space, wherein a sidewall among the plurality of sidewalls defined by the extended bottom surface is bent to define a second guiding portion extended from an uppermost end of the sidewall such that a thickness of the sidewall which defines the second guiding portion is substantially the same as a thickness of the second guiding portion defined thereby, the second guiding portion defined by the extended sidewall is spaced apart from the bottom surface and includes a first protrusion spaced apart from the bottom surface and inwardly protruded toward the receiving space, and the first protrusion spaced apart from the bottom surface is coupled with the recess of the first guiding portion of the light guide plate and does not overlap the light guide plate at the recess thereof in a plan view.
