Abstract: An imaging device is provided. The imaging device may include a substrate having a first photoelectric conversion unit and a second photoelectric conversion unit at a light-incident side of the substrate. The second photoelectric conversion unit may include a photoelectric conversion layer, a first electrode, a second electrode above the photoelectric conversion layer, a third electrode, and an insulating material between the third electrode and the photoelectric conversion layer, wherein a portion of the insulating material is between the first electrode and the third electrode.
