Abstract: In a backlight assembly and an LCD apparatus including a receiving unit formed by an injection molding process, a plurality of sidewalls is protruded from a bottom plate, and a receiving space is defined by the sidewalls and the bottom plate. A strength-reinforcing member is formed on a rear surface of the bottom plate to thereby reinforce a bending strength of the bottom plate. Accordingly, the receiving unit for receiving a lamp unit is formed using a material used with an injection molding process, and the strength-reinforcing member reinforces the bending strength of the bottom plate. Cost and weight of the backlight assembly and the LCD apparatus may be sufficiently reduced.
