Zusammenfassung:A pixel substrate includes a photoelectric conversion element. The photoelectric conversion element includes a doped region and a substrate region. The doped region and the substrate region form a pn junction. A pixel circuit is electrically connected to a first supply line and the photoelectric conversion element. A protection circuit is configured to short-circuit the first supply line and the substrate region when a voltage difference between the first supply line and the substrate region falls below a negative threshold voltage.
