摘要：
A display device having a plurality of pixels, each pixel includes a light-emitting element, a storage capacitor, a driving transistor, a first switching transistor which supplies a data voltage to the storage capacitor in response to an on-voltage of a scanning signal, a second switching transistor which diode-connects the driving transistor in response to an on-voltage of a compensation signal, and a third switching transistor which supplies a driving voltage to the driving transistor in response to an on-voltage of a light emitting signal. The storage capacitor stores a control voltage depending on a threshold voltage of the driving transistor when the driving transistor is diode-connected, transmits the control voltage and the data voltage to the control terminal of the driving transistor, and a period in which the compensation signal is in an on-voltage state is longer than a period in which the scanning signal is in an on-voltage state.
