Abstract: According to one embodiment, a semiconductor substrate includes a first basement, a gate line, a source line, an insulating film, a first pixel electrode, and a first transistor and a second transistor connected parallel at positions between the source line and the first pixel electrode. Each of a first semiconductor layer of the first transistor and a second semiconductor layer of the second transistor includes a first region, a second region, and a channel region. The first semiconductor layer and the second semiconductor layer are in contact with a first surface that is a surface of the insulating film on the source line side. The channel region of each of the first semiconductor layer and the second semiconductor layer wholly overlaps the gate line.

Abstract: The display device includes at least one pixel having a first capacitive element having a first terminal and a transistor connected to the first terminal and having a second terminal and a gate electrode. A driving method of the display device including in a first frame, a signal with a first pulse width is supplied to the gate electrode of the transistor, and a first voltage is written from the second terminal to the first terminal. In the second frame after the first frame, a signal with a second pulse width is supplied to the gate electrode, and the first terminal holds the first voltage. In the third frame after the second frame, a signal with a third pulse width is supplied to the gate electrode, and the second voltage is written from the second terminal to the first terminal.
