Patent ID: 8439545

Claim:
A backlight assembly comprising: a light source including a light emitting surface through which a light exits; and an optical member including a first surface disposed adjacent to the light source and a second surface disposed substantially opposite to the first surface, wherein the optical member covers the light source and guides the light therethrough, wherein the optical member comprises: an incident surface to which the light is incident, the incident surface being connected with the first surface corresponding to the light source; an optical pattern disposed on the second surface and corresponding to the light source, the optical pattern reflecting a first light of the light incident through the incident surface through total internal reflection; and a light guide pattern disposed on the first surface, wherein the light guide pattern directs the reflected first light to exit to an exterior of the optical member, wherein the incident surface is inclined toward a center of the light emitting surface as viewed from a cross-sectional perspective and the light incident to the optical member through the incident surface travels to the optical pattern.
