Abstract

An organic light emitting diode display includes: a substrate; an overlapping layer on the substrate; a pixel on the substrate and the overlapping layer; and a scan line, a data line, a driving voltage line, and an initialization voltage line that are connected to the pixel. The pixel includes: an organic light emitting diode; a second transistor connected to the scan line and the data line; a driving transistor including a gate electrode, an input terminal, and an output terminal, and to apply a current to the organic light emitting diode from the output terminal; and a voltage application transistor to apply a voltage to the overlapping layer. An output of the second transistor is connected to the input terminal of the driving transistor, and the overlapping layer is between the driving transistor and the substrate while overlapping with the driving transistor on a plane.
