An organic light emitting diode display includes: a substrate; a scan line, a first emission control line, and a second emission control line on the substrate; a data line and a driving voltage line crossing the scan line; a switching transistor connected to the scan line and the data line and including a switching drain electrode; a driving transistor including a driving source electrode connected to the switching drain electrode; an organic light emitting diode electrically connected to a driving drain electrode of the driving transistor; an operation control transistor to transmit a driving voltage to the driving transistor; and a first emission control transistor and second emission control transistor to transmit the driving voltage from the driving transistor to the organic light emitting diode, wherein the first emission control line and the second emission control line partially overlap each other.
