Abstract: A detection device includes a substrate having a detection region, a plurality of photodiodes provided in the detection region, a first light-transmitting resin layer that is provided so as to cover the photodiodes and comprises a flat portion and a periphery that is formed to be gradually thinner toward an end on a peripheral side of the first light-transmitting resin layer, a light-blocking layer that is provided on the first light-transmitting resin layer and provided with an opening in a region overlapping each of the photodiodes, and a plurality of lenses provided so as to overlap the respective photodiodes. In a region of the periphery of the first light-transmitting resin layer extending along a predetermined side, an asperity pattern is repeatedly formed in a direction intersecting the side and repeatedly formed in a direction along the side.

Abstract: According to an aspect, a detection device includes: a substrate having a detection region; a plurality of photodiodes provided in the detection region; a first light-transmitting resin layer provided so as to cover the photodiodes; a light-blocking layer provided on the upper side of the first light-transmitting resin layer and provided with openings in regions overlapping the respective photodiodes; a second light-transmitting resin layer provided so as to cover the light-blocking layer; and a plurality of lenses provided on the upper side of the second light-transmitting resin layer so as to overlap the respective photodiodes. The second light-transmitting resin layer is provided so as to cover an end on a peripheral side of the light-blocking layer on a peripheral side of the substrate.
