Patent ID: 8277105

Claim:
A backlight assembly comprising: a light source that emits light; and a light guide plate that receives the light, that changes a path of the light, and that outputs the light, wherein the light guide plate comprises: an incident surface to which the light is incident and that is adjacent to the light source, an exiting surface from which the light exits and that extends from a first end of the incident surface, a reflection surface that extends from a second end of the incident surface and that faces the exiting surface, a recessed-carving scattering pattern of recesses on the reflection surface toward the exiting surface to scatter the light incident to the light guide plate, the recesses having a depth-to-width ratio of about 0.2 to about 0.33 and the reflection surface having an uneven surface roughness, a reflection sheet disposed adjacent the reflection surface to reflect light leaked from the light guide plate back toward the light guide plate, and an embossment adjacent to a respective recess, the embossment protruding from the reflection surface to separate the reflection sheet and the reflection surface.
