| Zusammenfassung: | In one embodiment, a wiring open detection circuit includes a signal processing circuit, a terminal, a diode, and an open decision circuit. The signal processing circuit is connected to one end of a first wiring and outputs a signal processed signal to the first wiring. The terminal is connected to the other end of the first wiring. The diode has one end connected to the terminal. The open decision circuit applies a first voltage to the other end of the diode, and detects change in a current flowing in the first wiring to decide whether or not the first wiring is open. |
