Abstract
An off-leakage current of a photodiode is reduced in a photoelectric conversion device. A photoelectric conversion device () includes: an oxide semiconductor layer () provided on a substrate (); a passivation film () and a planarizing film () which are stacked on the oxide semiconductor layer; and a photodiode () including a lower electrode (), a photoelectric conversion layer (), and an upper electrode (). The lower electrode is connected to a source electrode () via a contact hole provided in the passivation film and the planarizing film. No photoelectric conversion layer is provided directly above the contact hole.
