Abstract: A display apparatus includes a backlight assembly which provides a light and a display panel which receives the light provided from the backlight assembly to display an image. The backlight assembly includes a light source which generates the light, and a light guide plate. The light guide plate receives the light generated from the light source through an incident surface thereof as an incident light, and outputs the incident light through an exit surface thereof as an exit light. The light guide plate includes a first optical pattern and a second optical pattern. The first optical pattern is disposed corresponding to a first area of the exit surface and collects the incident light. The second optical pattern is disposed corresponding to a remaining second area of the exit surface excluding the first area, and collects the exit light.

Abstract: A backlight unit includes a light source that emits light and a light guide plate disposed adjacent to the light source. The light guide plate includes an incident surface to which light is incident, an exit surface from which light incident through the incident surface exits, a reflection surface facing the exit surface to reflect the incident light, and a plurality of lenticular protrusions disposed on the exit surface. The reflection surface includes an inclined surface proximal to the incident surface and inclined with respect to the exit surface.
