1. A light detecting device, comprising:
a first photoelectric conversion unit disposed above a substrate, the substrate comprising a first surface and a second surface opposite to the first surface, the first surface being disposed between the first photoelectric conversion unit and the second surface, and the first photoelectric conversion unit comprising:
a first electrode;
a second electrode disposed between the first electrode and the substrate; and
a photoelectric conversion layer disposed between the first electrode and the second electrode;
a second photoelectric conversion unit disposed in the substrate, the second photoelectric conversion unit overlapping the first photoelectric conversion unit in a plan view;
a gate electrode, at least a portion of the gate electrode being disposed in the substrate and overlapping the second photoelectric conversion unit in the plan view;
a wiring layer disposed between the first surface of the substrate and the second electrode; and
a first floating diffusion region disposed in the substrate, the first floating diffusion region being disposed at a side of the second surface,
wherein at least a portion of the second photoelectric conversion unit is disposed between the first surface and the gate electrode, and
wherein the first floating diffusion region is configured to receive a charge generated in the photoelectric conversion layer through at least the second electrode and the wiring layer.
