Abstract

An imaging device comprises at least one unit pixel cell. Each of them comprises: a photoelectric conversion layer having a first and second surfaces; a pixel electrode and a shield electrode located on the first surface and separated from each other, a shield voltage being applied to the shield electrode; an upper electrode located on the second surface and opposing to the pixel electrode and the shield electrode, a counter voltage being applied to the upper electrode; a charge accumulation node electrically connected to the pixel electrode; and a charge detection circuit electrically connected to the charge accumulation node. The charge detection circuit includes a reset transistor that sets the pixel electrode at an initialization voltage at predetermined timing. An absolute value of a difference between the shield voltage and the counter voltage is larger than an absolute value of a difference between the initialization voltage and the counter voltage.
