Abstract: According to an aspect, a detection device includes: a detection element formed on a substrate; a photodiode provided in the detection element; partial photodiodes included in the photodiode; an organic protective film covering the partial photodiodes; lenses provided so as to overlap the partial photodiodes; a first light-blocking layer between the organic protective films and the lenses and provided with first openings in regions overlapping the partial photodiodes; a second light-blocking layer between the first light-blocking layer and the lenses and provided with second openings in regions overlapping the partial photodiodes and the first openings; a first light-transmitting resin layer provided between the first light-blocking layer and the second light-blocking layer; and a second light-transmitting resin layer provided between the second light-blocking layer and the lenses. The first light-blocking layer is provided on the organic protective film so as to be directly in contact with the organic protective film.
