Abstract
A pixel electrode includes a first electrode, a second electrode arranged so as to face the first electrode in a first direction, and a third electrode. A counter electrode is provided in an upper portion of the pixel electrode, and a photoelectric conversion layer is arranged so as to be sandwiched by the pixel electrode and the counter electrode. A length of the third electrode in a predetermined direction is shorter than a length of the first electrode and a length of the second electrode.
