Abstract:
A display device includes a lower cover; a circuit substrate disposed on the lower cover; a plurality of light sources disposed on the circuit substrate; a reflection layer disposed on the circuit substrate; a light regulator disposed at an edge of the reflection layer at an angle with respect to the reflection layer; and an optical sheet disposed on the plurality of light sources. Further, the light regulator includes a reflector portion reflecting light from the plurality of light sources; and an absorber portion having holes arranged in a pattern. In addition, light emitted from a respective light source close to the edge passes through the holes.
