Liquid crystal display device and liquid crystal display device driving method
Abstract:
A liquid crystal display device 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 reaching a first electric potential at a first timing after the change is initiated, and the common electrode being in an electrically floating state at a second timing which comes after the first timing. This, in a case where the transistor is turned on in preparation for an operation to turn off a power source of the liquid crystal display device, makes it unlikely for a DC voltage to be applied across a pixel even if potential variation (kickback) occurs at the pixel electrode in reaction to a change in status of the transistor from an on state to an off state.
