1. An organic light emitting diode display comprising:
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,
wherein the pixel comprises:
an organic light emitting diode;
a second transistor connected to the scan line and the data line;
a driving transistor comprising a gate electrode, an input terminal, and an output terminal, and configured to apply a current to the organic light emitting diode from the output terminal; and
a voltage application transistor configured to apply a voltage to the overlapping layer,
wherein the overlapping layer is between the driving transistor and the substrate, and overlaps the driving transistor.
