Abstract
According to an aspect, a detection device includes: a substrate; a photodiode in which a lower electrode, a semiconductor layer, and an upper electrode are stacked on the substrate in the order as listed; a transistor provided in the photodiode; an insulating layer provided between layers of the substrate and the photodiode; and a planarizing layer covering the insulating layer. The insulating layer comprises a projecting portion that projects toward the photodiode in a direction orthogonal to the substrate. The planarizing layer has a contact hole provided in a position that is below the photodiode and overlaps the projecting portion of the insulating layer. The photodiode is provided on an upper side of the planarizing layer and is also provided so as to cover the contact hole. The lower electrode of the photodiode is electrically coupled to the transistor at a bottom of the contact hole.
