Abstract
A display device includes a switch, an initialization line, a capacitor, a data line, a first transistor, a second transistor, a driving transistor, and a diode. The capacitor includes a first electrode and a second electrode. To the first electrode through at least the initialization line, the switch may output a first voltage in a first period of a horizontal time and may output a second voltage unequal to the first voltage in a second period of the horizontal time. The first transistor may connect the data line to the first electrode in response to a scan signal. The driving transistor may provide a driving current based on a voltage of the first electrode. The second transistor may connect the initialization line to the second electrode in response to an initialization signal. The diode may emit light based on the driving current.
