发明名称 Liquid crystal display device
摘要 A liquid crystal display device preventing flicker. The liquid crystal display device includes a plurality of pixels each having a transistor, a liquid crystal element to which a first signal and a second signal having opposite polarities are alternately applied through the transistor, and a capacitor including a first electrode and a second electrode. The liquid crystal element includes a pixel electrode and a common electrode partly overlapping with each other with an insulating film interposed therebetween, and a liquid crystal layer over the pixel electrode and the common electrode. The first electrode of the capacitor is electrically connected to the pixel electrode. The potential of the second electrode changes between a first potential and a second potential having different levels after the first signal is applied until the second signal is applied, whereby a change in the voltage applied to the liquid crystal layer is reduced.

主权项 1. A liquid crystal display device comprising: a pixel comprising: a transistor;a liquid crystal element including a pixel electrode, a common electrode, and a liquid crystal layer over the pixel electrode and the common electrode, wherein a first signal and a second signal having opposite polarities are alternately supplied to the pixel electrode through the transistor, and wherein a fixed potential is supplied to the common electrode; anda capacitor including a first electrode and a second electrode, wherein the pixel electrode and the common electrode partly overlap with each other with an insulating film interposed therebetween, wherein the first electrode is electrically connected to the pixel electrode, and wherein the second electrode is connected to a wiring to which a potential which changes between a first potential and a second potential is applied.
