Abstract: An organic light-emitting device includes an oxide semiconductor layer disposed in a pixel area. The oxide semiconductor layer includes a channel region, a source region and a drain region. A gate insulating layer is disposed on the oxide semiconductor layer. A gate electrode is disposed on the gate insulating layer. A conductive layer is disposed between the substrate and the oxide semiconductor layer. A bridge electrode is in contact with the conductive layer and one of the source region and the drain region. A first insulation film covers the gate electrode and the bridge electrode. An organic light-emitting diode includes a pixel electrode. An emissive layer is disposed on the pixel electrode, and an opposite electrode is disposed on the emissive layer. At least a portion of the oxide semiconductor layer overlaps the organic light-emitting diode. The conductive layer includes a light transmittance material.

Abstract: A display panel that includes a plurality of pixels, each pixel includes a first area including a display device; a second area including a first reflective member to reflect light received from the display device to an outside of the display panel for viewing, and a third area including a second reflective member reflecting external light to provide a mirror function when the display device is not displaying an image. The display device includes a pair of reflective electrodes to cause the light produced by the display device to propagate towards the second area. One of the two electrodes may further include a transparent conductive material to provide a waveguide function to the display device in the first area to improve coupling efficiency of the display panel.
