发明名称 LIQUID CRYSTAL DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE DRIVING METHOD
摘要 The present invention is intended to make it unlikely that, in a case where a transistor is turned on in preparation for an operation to turn off a power source of a liquid crystal display device, a DC voltage becomes applied across a pixel even if potential variation (kickback) occurs at a pixel electrode in reaction to a change in status of the transistor from an on state to an off state. A liquid crystal display device of the present invention includes: a data signal line; a scan signal line; a pixel electrode; a transistor connected to (i) the data signal line, (ii) the scan signal line, and (iii) the pixel electrode; and a common electrode, the liquid crystal display device being configured to turn on the transistor during a power-off sequence by causing a change in an electric potential of the scan signal line, the electric potential of the scan signal line increasing up to a first electric potential at a first timing after the change is initiated, and an output electric potential supplied to the data signal line at a second timing which comes after the first timing being set to a value higher than an output electric potential supplied to the common electrode at the second timing.
