Abstract: A reflective sheet with a dot-cut pattern for preventing both bright line and bright spot, and a method of manufacturing the same, is provided. The reflective sheet and method of manufacturing the same may be capable of reducing a manufacturing cost and also improving a manufacturing efficiency. The reflective sheet may include a bottom part including a hole for exposing a light source, the bottom part provided on a bottom surface of a cover bottom; a lateral part extending from the bottom part, the lateral part provided at a lateral surface of the cover bottom; a half-cut pattern formed in the boundary between the bottom part and the lateral part; and a plurality of dot-cut patterns formed at the lateral part.

Abstract: Light can be uniformly distributed in the bezel area by diffusing the light in the bezel area blocked by an upper case, or by providing an optical pattern for light concentration. Accordingly, the brightness of light is similar for all positions at the boundary between the bezel area and the display area, thereby solving the hot spot problem caused by a brightness difference depending on position.
