ABSTRACT:
The present invention provides a liquid crystal display device which can recover a charge stored in a liquid crystal display panel without using an exteriorly mounted part such as a coil thus achieving the low power consumption. A display device includes a liquid crystal display panel having a plurality of pixels, a plurality of video lines which apply a video voltage to the plurality of pixels, and a drive circuit which supplies the video voltage to the plurality of video lines. In such a display device, the liquid crystal display panel has a common electrode to which a first voltage and a second voltage having a potential higher than a potential of the first voltage are alternately applied. The liquid crystal display panel further includes a charge recovering circuit which is connected between the respective video lines and a power source line and recovers charge when a voltage applied to the common electrode is changed over from the first voltage to the second voltage or when the voltage applied to the common electrode is changed over from the second voltage to the first voltage.
