Abstract: A display device capable of reducing a non-display area includes a substrate hole surrounded by light emitting elements, and a moisture penetration preventing layer disposed between an inner dam surrounded by the light emitting elements and the substrate hole. Accordingly, it is possible to prevent damage to light emitting stacks caused by external moisture or oxygen. Since the substrate hole is disposed within an active area, a reduction in non-display area is achieved.

Abstract: Disclosed is an organic light emitting display having a mirror function. In an embodiment, a light-shielding reflective layer overlaps areas of the organic light emitting display except for emission areas provided with light emitting devices formed therein. The light-shielding reflective layer prevents light from entering channel regions of active layers and reflects external light, for example, when the organic light emitting device is not operated to display an image, and thus the organic light emitting display may stably implement a mirror function.
