An object of one embodiment of the present invention is to provide a liquid crystal display device using the common inversion driving that allows the amplitude voltage of a scan signal on a scan line to be low. The device including a first transistor having a gate, a first terminal, and a second terminal electrically connected to a scan line, a signal line, and a first electrode of a liquid crystal element, respectively; and a second transistor having a gate, a first terminal, and a second terminal electrically connected to the scan line, a common potential line, and a second electrode of the element, respectively. An image signal is supplied from the signal line to the first electrode to subject the element to inversion driving. A common potential is supplied from the common potential line to the second electrode in synchronization with supply of the image signal.
