Abstract: A backlight assembly includes a receiving container including a bottom plate having a lower face and an upper face opposite the lower face, a sidewall part protruding from edge portions of the bottom plate, and a plurality of light property controlling parts disposed on the upper face and having a substantially wedge shaped cross-section. The backlight further includes a light source disposed between adjacent light property controlling parts, and the light source is received by the receiving container, wherein a distance between a center of the light source and the upper face is substantially equal to a height of at least one of the plurality of light property controlling parts. The backlight assembly may increase the brightness and brightness-uniformity of light.

Abstract: A light-diffusing member includes a first face, a second face arranged opposite to the first face, and a light-diffusing portion including at least one valley and at least one ridge that are alternatively arranged. A first thickness of the light-diffusing member between the ridge and the first face is about 1.15 to about 1.80 times greater than a second thickness of the light-diffusing member between the valley and the first face.

Abstract: A backlight assembly includes a receiving container and a light source. The receiving container includes a bottom plate having a lower face and an opposing upper face, a sidewall part, and a plurality of light property controlling parts having a substantially wedge shaped cross-section, which extend substantially parallel to a pair of first sidewalls of the sidewall part. The light source is disposed between adjacent light property controlling parts, and the light source is received by the receiving container. The backlight assembly may increase the brightness and brightness-uniformity of light.

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.
