Abstract: A liquid crystal display includes a first pixel and a second pixel that extend in a data line direction. The first and second pixels are connected to a same data line, and the first pixel is closer to a data driver than the second pixel. A channel width of a thin film transistor of the first pixel is less than a channel width of a thin film transistor of the second pixel.

Abstract: A stage includes an output, first and second controllers, and first and second inputs. The output supplies a scan signal to a first output terminal and a carry signal to a second output terminal based on first and second node voltages and a first clock signal supplied to a first input terminal. The first controller controls a third node voltage based on a voltage of the second output terminal. The second controller controls the second node voltage based on the first clock signal supplied to the first input terminal and the third node voltage. The first input controls the first and third node voltages based on a carry signal of a previous stage supplied to a second input terminal. The second input controls the first and third node voltages based on the second node voltage and a carry signal of a next stage supplied to a third input terminal.
