Abstract

A pixel has a simple structure and compensates for a threshold voltage of a driving transistor. An organic light emitting display device includes the pixel, which includes: an organic light emitting diode; a first transistor having a second electrode coupled to the organic light emitting diode and a first electrode coupled to a data line; a second transistor between a gate electrode and the second electrode of the first transistor and turned on when a scan signal is supplied to a scan line; and a storage capacitor electrically coupled between the gate electrode of the first transistor and a first power supply.
