A driver circuit includes a circuit 200 , a transistor 101 — 1, and a transistor 101 — 2 . A signal is selectively input from the circuit 200 to a gate of the transistor 101 — 1 and the transistor 101 — 2, so that the transistor 101 — 1 and the transistor 101 — 2 are controlled to be on or off. The transistor 101 — 1 and the transistor 101 — 2 are turned on or off; thus, the wiring 112 and the wiring 111 become conducting or non-conducting. |
