Document Type and Number:
WIPO Patent Application WO/2023/223877
Kind Code:
A1
Abstract:
This detection device comprises a substrate and a photodiode disposed on the substrate in which a lower electrode, a lower buffer layer, an active layer, an upper buffer layer, and an upper electrode are stacked in this order. In a plan view, the lower electrode is provided extending from a region overlapping an organic semiconductor layer including the lower buffer layer, the active layer, and the upper buffer layer, to a region outside a side surface of the organic semiconductor layer. Further, a detection device comprises a plurality of the photodiodes, wherein a plurality of the lower electrodes are arrayed respectively corresponding to the plurality of photodiodes and extend to a region outside the side surface of the organic semiconductor layer in at least a first direction. A plurality of the photodiodes are arrayed in a second direction intersecting the first direction, and the upper electrode is provided extending across the plurality of photodiodes in the second direction.
