LIQUID CRYSTAL DISPLAY DEVICE, DRIVING METHOD OF THE SAME, AND ELECTRONIC APPLIANCE INCLUDING THE SAME

摘要

An object is to provide a liquid crystal display device in which low power consumption can be achieved. A first substrate includes a terminal portion, a switching transistor, and a pixel circuit including a pixel electrode is provided. A second substrate includes a counter electrode. A liquid crystal element is interposed between the pixel electrode and the counter electrode. A potential to be input to the counter electrode is supplied from a terminal portion through the switching transistor. A semiconductor layer included in the switching transistor is an oxide semiconductor layer.
