1. A display device comprising:
a display unit comprising pixels arranged in a plurality of pixel lines; a scan driver for respectively transmitting a corresponding plurality of scan signals to the plurality of pixel lines during a corresponding plurality of horizontal periods of one frame, the one frame comprising an initialization period followed by all of the plurality of horizontal periods; a data driver for transmitting data signals to the pixels after the initialization period and during the plurality of horizontal periods, the data signals for storing corresponding data voltages in the pixels; and an initialization control driver for concurrently generating and transmitting an initialization signal to all of the pixels during the initialization period of the one frame separate from and preceding any and all of the plurality of horizontal periods of the one frame, to concurrently initialize the data voltages corresponding to the data signals of a previous frame stored in all of the pixels during the initialization period and before any and all of the plurality of horizontal periods, wherein
the scan driver comprises a plurality of shift registers for generating the scan signals respectively corresponding to the plurality of pixel lines, anda shift register of the plurality of shift registers is configured to receive, as a first input signal, one of the scan signals generated from one of the plurality of shift registers adjacent to the shift register in synchronization with a first clock signal, to transmit the first input signal through a first switch in response to the first clock signal, to transmit a second clock signal through a second switch in response to the first input signal as transmitted through the first switch, and to output, as another one of the scan signals, either the second clock signal as transmitted through the second switch or a first power supply voltage corresponding to the first input signal.
