Abstract:
1. A backlight assembly, comprising: a total reflection plate having an upper surface, a lower surface, and a side surface, the total reflection plate configured to selectively totally internally reflect light incident to the side surface and to transmit light incident on the lower surface to the upper surface; a first light source to emit the light incident to the side surface; a second light source to emit the light incident to the lower surface; and an array sheet disposed on the total reflection plate, comprising a plurality of units each having an incident surface making contact with the total reflection plate and an emitting surface facing the incident surface, each unit to refract the totally internally reflected light at a contact surface between the incident surface and the total reflection plate, to emit the refracted light, and to emit the transmitted light as a non-refracted light, wherein the refracted light is configured to form a 3D stereoscopic image and the transmitted light is configured to form a 2D image.
