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.

Abstract: An imaging device includes a semiconductor substrate and pixels, which includes a first pixel and second pixels adjacent thereto. Each of the pixels includes a first photoelectric conversion layer, a first pixel electrode, a first plug that electrically connects the semiconductor substrate and the first pixel electrode, a second photoelectric conversion layer, a second pixel electrode, and a second plug that electrically connects the semiconductor substrate and the second pixel electrode. In the first pixel and the plurality of second pixels, a distance between the closest plugs of the first plugs and the second plugs is larger than or equal to one-half of a pixel pitch, when viewed in a normal direction of the semiconductor substrate.
