Claim Text:
1. A liquid crystal display device comprising: 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, wherein the transistor is an n-channel transistor, the liquid crystal display device turns 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 reaches a first electric potential at a first timing after the change is initiated, after reaching the first electric potential at the first timing, the electric potential of the scan signal line decreases and reaches a second electric potential at a second timing that occurs after the first timing, the common electrode is in an electrically floating state at the second timing, and the second electric potential is higher than a threshold potential of the transistor.
