Abstract: A scan driver includes stages, each of the stages receiving first and second clock signals having a first low level as an active level, and a third clock signal having a high level as the active level. Each of the stages includes a logic circuit that changes a voltage of a first node to the first low level based on an input signal and the first clock signal, and changes a voltage of the first node to a second low level lower than the first low level based on the second clock signal, a first output buffer that outputs, as an active-low scan signal, the second clock signal in response to the voltage of the first node, and a second output buffer that outputs, as an active-high scan signal, the third clock signal in response to the voltage of the first node.

Abstract: A liquid crystal display includes a first substrate and a second substrate facing each other. The liquid crystal display further includes a gate line and a data line disposed on the first substrate, a first thin film transistor and a second thin film transistor connected to the gate line and the data line, a first subpixel electrode connected to the first thin film transistor, a third thin film transistor connected to the second thin film transistor, a second subpixel electrode connected to the third thin film transistor; and a liquid crystal layer interposed between the first substrate and the second substrate. The third thin film transistor includes a first terminal applied with a same constant voltage during all times of operation, a second terminal directly connected to the second thin film transistor, and a third terminal connected to the second subpixel electrode.
