The present invention relates to a display device. The display device includes a liquid crystal panel which selectively transmits light to each pixel; a light guide plate located on the back surface of the liquid crystal panel; a light resource array which includes multiple LEDs adjacent to one side of the light guide plate in parallel, and supplies light to the one side of the light guide plate; a mirror which is located on the other side of the light guide plate, moves along the light guide, and reflects light reaching the other side; and a stepped recess which is formed on the back side of the light guide plate and includes multiple surfaces having different angles from adjacent surfaces. The thickness of the light guide plate gradually increases from one side to the other side. So, the brightness of a display part can be controlled. |
