Patent ID: 8507963

Claim:
A photoelectric conversion device comprising: a thin-film transistor formed on a substrate; and a photo diode electrically connected to the thin-film transistor, wherein the photo diode comprises: a lower electrode connected to a drain electrode of the thin-film transistor; a photoelectric conversion layer formed on the lower electrode; an upper electrode formed from a transparent conductive film on an upper surface of the photoelectric conversion layer, the upper electrode being formed so as to be contained within the upper surface of the photoelectric conversion layer as viewed from a top; a protective film formed so as to protect a part of an upper surface of the photoelectric conversion layer located outside the upper electrode; and a passivation layer which is separate from and thicker than the protective film, the passivation layer being provided over and contacting at least part of an upper surface of the upper electrode and at least part of an upper surface of the protective film, the passivation layer having an opening through which a conductive line makes contact with the upper surface of the upper electrode.
