A second control signal bus line receives a second control signal that lags behind the first control signal. A de-multiplexer circuit includes a first switching element and a second switching element. The first switching element switches a current path between a first source line and a first data line in response to the first control signal, and the second switching element switches a current path between the first source line and a second data line in response to the second control signal. A pixel part includes a first pixel connected to the first control signal bus line and corresponding to a first color filter, a second pixel connected to the second control signal bus line and corresponding to a second color filter, and a third pixel corresponding to a third color filter, wherein the third pixels are alternately connected to the first control signal bus line and the second control signal bus line.

Abstract:
A scan driver drives a display device having a plurality of gate lines transferring scan signals, and a plurality of source lines transferring data signals. The scan driver includes a shift register and a multiple signal applying unit. The shift register includes a plurality of cascade-connected stages, each stage having an output terminal electrically connected to a respective one of the plurality of gate lines. The multiple signal applying unit applies a sub scan signal and a main scan signal. The sub scan signal and the main scan signal sequentially activate each of the plurality of gate lines. Therefore, the scan lines receive the scan signal twice, so that the liquid crystal capacitors electrically connected to the gate lines receive the data voltage twice. As a result, even though the time for charging the liquid crystal capacitors may be reduced, the liquid crystal capacitors may be fully charged to enhance display quality.

Each first stage outputs the first gate-on voltage based on a third gate-on voltage of the carry signal from a previous second stage, and each second stage outputs the second gate-on voltage based on the third gate-on voltage of the carry signal from the previous second stage.
