Abstract:
1. An organic light emitting diode display comprising: a substrate; a gate line and a data line which intersect each other and are disposed on the substrate; a driving voltage line transmitting a driving voltage and intersecting the gate line; and a pixel, each pixel comprising: a switching transistor; a driving transistor connected to the switching transistor; a first electrode connected to the driving transistor; a second electrode facing the first electrode; and a light emitting member disposed between the first electrode and the second electrode, wherein the switching transistor comprises: a switching control electrode connected to the gate line; a switching input electrode connected to the data line; a switching output electrode disposed substantially opposite the switching input electrode with respect to the switching control electrode; and a switching semiconductor which overlaps the switching control electrode, and wherein the driving transistor comprises: a lower driving control electrode disposed on the substrate and directly connected to the switching output electrode with a connecting member; a driving semiconductor disposed on the lower driving control electrode with respect to the substrate and overlapping the lower driving control electrode; and a driving input electrode and a driving output electrode which opposes each other with respect to the driving semiconductor, wherein the lower driving control electrode and an upper driving control electrode are physically separated from each other and opposing each other with the driving semiconductor interposed therebetween in a cross-sectional view in each pixel, and the lower driving control electrode, the driving semiconductor, and the upper driving control electrode are sequentially arranged in a direction perpendicular to a surface of the substrate.
