Backlight assembly and display device having the same

摘要

A light guide apparatus includes a reflecting polarizing surface and a light reflecting surface having at least one prism pattern thereon. The light guide apparatus may improve image display quality and manufacturing cost. For example, a backlight assembly includes a lamp, a light guiding plate and a reflecting sheet. The light guiding plate includes a light incident surface, a light reflecting surface and a light exiting surface. The light generated from the lamp is incident into the light incident surface. The light reflecting surface is extended from a side of the light incident surface. A plurality of first prism patterns is formed on the light reflecting surface. The light exiting surface is extended from another side of the light incident surface to correspond to the light reflecting surface. A reflective polarizing layer is formed on the light exiting surface. The reflecting sheet is on the light reflecting surface.
