    摘要： A display device includes a display panel for displaying a still image and for displaying a motion picture. The display panel includes a gate line, a data line, a storage electrode line, a first switching element connected to the gate line and the date line, a storage connected to the switching element and the storage electrode line. The display device further includes a signal controller for providing controlling signals to drive the display panel. The display panel is driven at a first frequency when the motion picture is displayed. The display panel is driven at a second frequency lower than the first frequency when the still image is displayed. When the display panel is driven at the second frequency, a common voltage inputted to the storage electrode line changes.
