BACKLIGHT ASSEMBLY AND DISPLAY APPARATUS HAVING THE SAME

摘要

PURPOSE: A backlight assembly and a display device with the same are provided to actively control distribution of light emitted from the backlight assembly. CONSTITUTION: Light of light sources(200) is incident onto a light incident surface(310) of a light guide plate(300). A light emitting surface of the light guide plate emits the incident light. A zigzag pattern is formed on a light facing surface of the light guide plate. The thickness of the light guide plate gradually increases from the light incident surface to the light facing surface. A cross line is a straight line which is made when the light emitting surface crosses the light facing surface. A prism sheet(400) converts the direction of the light emitted from the light guide plate into a direction perpendicular to the light emitting surface.
