摘要： In one embodiment of the present invention, on each source bus line, an electric charge escaping transistor is provided having the same polarity as a pixel transistor and having a gate to which a turn-off voltage signal of the pixel transistor is supplied. When an active matrix liquid crystal display device is powered off, the turn-off voltage signal is made to reach the GND level before a turn-on voltage signal of the pixel transistor reaches the GND level, so that the pixel transistor and the electric charge escaping transistor are made half-open. This lets electric charges accumulated in the pixel escape to a common electrode TCOM.
