The present invention relates to a display device, comprising: a plurality of scan signal lines, a plurality of data lines intersecting the scan signal lines, a switching transistor connected to the scan signal line and the data line, and a driving transistor connected to the switching transistor. And a plurality of pixels including a light emitting element connected to the driving transistor, a data driver for applying a data voltage to the data line, and a scan for applying a scan signal having at least three different voltage levels to the scan signal line. It includes a drive unit. Therefore, by supplying the reverse bias voltage to the driving transistor, a change in the threshold voltage of the driving transistor can be prevented, and the leakage current can be reduced by lowering the voltage of the control terminal of the switching transistor when the reverse bias voltage is supplied to the driving transistor.n n n n OLED display, threshold voltage, impulsive effect, scan driver |
