Abstract: A display apparatus includes a display panel having a first area and a second area, a main body supporting the display panel, an auxiliary member arranged in the main body, and a reflective member arranged between the auxiliary member and the display panel, wherein the reflective member may movably be provided to overlap the first area or the second area. Therefore, light emitted from the display panel toward the inside of the main body may be reflected in the outside, and a luminance difference between the first area and the second area of the display panel may be prevented from occurring, whereby a user's satisfaction for an image may be enhanced.
