Abstract: An organic light emitting diode display device comprises a substrate which includes a plurality of pixel regions each having a sub-pixel region and a transparent region. In each pixel region, an active layer is disposed in the sub-pixel region. A gate electrode overlaps the active layer. A first electrode is disposed on the active layer, and contacts the active layer. A second electrode is spaced apart from the first electrode, and contacts the active layer. A first lower electrode having a first thickness is disposed in the sub-pixel region and connected to the second electrode. A second lower electrode is disposed in the transparent region on the substrate, located at a same level as the gate electrode. The second lower electrode has a second thickness that is less than the first thickness, and is transparent.

Abstract: A display device may include a substrate, a first light emitting structure, a second light emitting structure, and a support structure. The first light emitting structure may include an electrode and a light emitting layer. A face of the electrode may directly contact the light emitting layer and may overlap the substrate. The support structure may be positioned between the first light emitting structure and the second light emitting structure, may be spaced from each of the first light emitting structure and the second light emitting structure, may overlap a transparent portion of the substrate, and may not include or directly contact any light emitting layer. A height of the support structure relative to the substrate may be greater than at least one of a height of the face of the electrode relative to the substrate and a height of the light emitting layer relative to the substrate.
