Abstract
A pixel includes an organic light emitting diode, a first transistor that is connected to a first power source and that supplies a driving current according to a corresponding data voltage to the organic light emitting diode, a second transistor that is connected to a scan line and that transmits the corresponding data voltage from a data line to a driving transistor according to a scan signal transmitted from the scan line, and a first capacitor including one electrode connected to a gate electrode of the first transistor. The first capacitor stores the corresponding data voltage as a first voltage and a size of the first capacitor is in a range of about 2 times to about 4 times a size of a gate insulating layer of the first transistor.
