摘要
A display device including: a scan driver that transmits scan signals to scan lines; a data driver that data signals to data lines; and a display portion that includes pixels, respectively connected to the corresponding scan lines and corresponding data lines, and displays an image by the pixels that simultaneously emit light according to the corresponding data signals, wherein each of pixels includes: an organic light emitting diode; a first transistor that includes a gate connected to a first node, and is connected between first power and an anode of the organic light emitting diode; a second transistor that includes a gate connected to a corresponding scan line and transmits the corresponding data signal to the first node; and a first capacitor that is connected to the first node, and stores a data voltage according to the data signal.

Thus, the first node N1, the second node N2, and the anode are all connected during the period ta3 to ta4 after the second node N2 and the anode are initialized back to the first voltage level ELVDD_L, and accordingly, the voltage of the first capacitor Cst, remaining even after the period ta2 to ta3, is initialized again.
During a period ta5 to tab, the scan signals S[1] to S[n] have the gate-on voltage level VGL, and then may have the gate-off voltage level VGH until before the threshold voltage compensation period PA2.
In addition, during the period ta5 to tab, the scan signals S[1] to S[n] have the gate-on voltage level VGL, and then may maintain the gate-on voltage level VGL until the threshold voltage compensation period PA2.
