    摘要： An organic light emitting diode display includes a plurality of pixels. At least one pixel is connected to a scan line receive a scan signal, a data line to receive a data signal, and voltage line to receive a driving voltage. The at least one pixel includes a switching transistor including a switching drain electrode to output the data voltage, a driving transistor including a driving source electrode connected to the switching drain electrode, and an organic light emitting diode connected to a driving drain electrode of the driving transistor. The driving source electrode is separated from the data line.
