Abstract: A display apparatus includes a display panel having a front area and a side area, a main body supporting the display panel, an auxiliary member arranged inside the main body, and a semi-transmissive mirror arranged between the auxiliary member and the front area, wherein the side area of the display panel may be arranged inside the main body to face the semi-transmissive mirror. Since an image partially emitted from the display panel may be reflected toward the front area, auxiliary members such as a camera, an illumination sensor, and a proximity sensor may be arranged inside the main body (or below a display) to embody a full screen display, whereby a user's satisfaction may be enhanced and a manufacturing process may be simplified.
