Abstract
A backlight assembly includes a light source part, a total reflection plate and an array sheet. The light source part generates light. The total reflection plate totally internally reflects or transmits the light selectively according to an incident path of the light. The array sheet disposed on the total reflection plate includes a plurality of units having an incident surface making contact with the total reflection plate and an emitting surface facing the incident surface, refracts the totally internally reflected light at a contact surface between the incident surface and the total reflection plate to emit the refracted light, and emits the transmitted light as a non-refracted light. Accordingly, luminance of the display device is enhanced.
