Abstract
An optical detector includes a stacked structure, an active layer, a gate insulating layer, and a gate electrode. The stacked structure includes a first electrode, a photoelectric conversion layer, a second electrode, a first insulating layer, and a third electrode. The active layer is electrically coupled to one of the first electrode or the second electrode, and electrically coupled to the third electrode. The gate insulating layer is arranged on the active layer. The gate electrode is arranged on the gate insulating layer.
