Abstract: An electroluminescent display device is disclosed. The electroluminescent display device includes a substrate having thereon a first sub pixel and a second sub pixel, a first electrode in each of the first sub pixel and the second sub pixel on the substrate, an organic layer with P-type polarity or N-type polarity on the first electrode, and a second electrode on the organic layer. The organic layer provided in the first sub pixel and the organic layer provided in the second sub pixel are spaced apart from each other with a doping layer provided in the boundary area between the first sub pixel and the second sub pixel. The doping layer is doped with dopant whose polarity is opposite to that of the organic layer.

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.
