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.

An organic light emitting display comprising:
- a light emitting device disposed in an emission area of a substrate, the light emitting device emitting internal light through the emission area of the substrate;
- a light-shielding reflective layer on the substrate overlapping a non-emission area of the substrate to reflect external light incident through the substrate;
- a plurality of thin film transistors on the substrate, the plurality of thin film transistors overlapping the light-shielding reflective layer, wherein the light-shielding reflective layer overlaps an area between the plurality of thin film transistors;
- and
- a plurality of pads on the substrate, wherein the light-shielding reflective layer overlaps the plurality of pads and an area between the plurality of pads.
An organic light emitting display comprising:
- a light emitting device configured to emit light through an emission area of a transparent substrate for displaying an image in a light emission mode;
- a pixel driving circuit coupled to the light emitting device and configured to drive the light emitting device, wherein the pixel driving circuit comprises a plurality of thin film transistors;
- a light-shielding reflective layer between the transparent substrate and the pixel driving circuit, the light-shielding reflective layer configured to reflect external light passing through the transparent substrate in a mirror mode, wherein the light-shielding reflective layer overlaps an area between the plurality of thin film transistors;
- and
- a plurality of pads on the transparent substrate, wherein the light-shielding reflective layer overlaps the plurality of pads and an area between the plurality of pads.
