Abstract
A liquid crystal display device includes a plurality of pixel driving circuits and a pixel array. Each pixel driving circuit of the plurality of pixel driving circuits includes four thin film transistors and has four output terminals, where each thin film transistor is used for driving an output terminal of the four output terminals, and the four output terminals are coupled to two gate lines and two sharing lines respectively for outputting two main output signals and two sharing output signals. The phases and timings of the two main output signals and the two sharing output signals are all the same. A pixel of the pixel array is charged/discharged to a specific voltage level according to a main output signal of the two main output signals, a sharing output signal, and a signal of a data line.
