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.
