Abstract: A light guide plate for a backlight. The light guide plate includes: a light source unit for generating light; a light guide plate proximate to the light source unit and including an upper surface and a lower surface; and a light emission pattern configured to diffuse a portion of the light directed toward an image display panel, and a first straight pattern configured to channel the light along a direction substantially parallel to a direction of propagation of the light generated by the light source unit, both the light emission pattern and the first straight pattern being disposed on one of the upper surface and the lower surface of the light guide plate, in which the first straight pattern has peaks and valleys formed in alternating and repeating manner in a direction substantially perpendicular to a direction of propagation of the light generated by the light source unit.

Abstract: A backlight assembly includes a light source generating light and a first optical member diffusing the light. The first optical member includes a first diffusion member provided on an exit surface of the first optical member, from which the light exits, to diffuse the light. The first diffusion member includes a plurality of edges each having a curved shape and extending between the exit surface and a vertex of the first diffusion member. Accordingly, the light exiting through the exit surface is effectively diffused by the edges of the first diffusion member.

Abstract: A display apparatus includes a display panel which receives light to display an image. A light guide plate guides the light toward the display panel. A light source unit is disposed at a first side of the light guide plate to provide the light to the light guide plate. The light source unit includes a printed circuit board which includes a first area and a second area. A first light source is disposed on the first area and generates the light. A first stepped part is disposed on the second area and faces the first light source. A first adhesive part is disposed on the second area. The first stepped part reflects the light which is generated from the first light source toward the light guide plate, and the first adhesive part attaches the printed circuit board to the light guide plate.
