Abstract:
1. A driving method of a liquid crystal display device, comprising the steps of: displaying an image on a screen provided with pixels each including a capacitor, a liquid crystal element, and a first transistor including a first oxide semiconductor layer by supplying a power source potential from a power source so that liquid crystals of the liquid crystal element respond; supplying a stop signal by a stop unit; displaying an initial-state image on the screen provided with the pixels by supplying a fixed potential to one electrode of the liquid crystal element through the first transistor, and to another electrode of the liquid crystal element through a second transistor including a second oxide semiconductor layer so that a state of the liquid crystals changes from a response state to a non-response state; and stopping the supply of the power source potential from the power source after writing the fixed potential to the capacitors, wherein each of the first oxide semiconductor layer and the second oxide semiconductor layer includes a channel region.
