PROBLEM TO BE SOLVED: To prevent reduction in a gate potential of a pull-up transistor.SOLUTION: A first transistor included in a driving circuit has a first terminal electrically connected to second wiring, a second terminal electrically connected to first wiring, and a gate electrically connected to a second circuit and a first terminal of a third transistor. A second transistor has a first terminal electrically connected to the first wiring, a second terminal electrically connected to sixth wiring, and a gate electrically connected to a first circuit and a gate of the third transistor. The third transistor has a second terminal electrically connected to the sixth wiring. The first circuit is electrically connected to third wiring, fourth wiring, fifth wiring, and the sixth wiring. The second circuit is electrically connected to the first wiring, the second wiring, and the sixth wiring. |
