Assignee: JAPAN DISPLAY INC.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G  Y | IPC G  H

Claim 0:
1. A detection device comprising:
a substrate;
a plurality of detection electrodes arranged in a detection area of the substrate;
an organic semiconductor layer covering the detection electrodes;
a counter electrode provided above the organic semiconductor layer; and
a plurality of first buffer layers,
wherein
the organic semiconductor layer includes at least either of a first p-type semiconductor layer and a first n-type semiconductor layer, and an active layer,
the active layer is provided in each overlapping area overlapping a corresponding one of the detection electrodes, and has a structure in which a p-type semiconductor and an n-type semiconductor are mixed and coexist,
the first p-type semiconductor layer or the first n-type semiconductor layer is provided in a non-overlapping area not overlapping the detection electrode, and is provided between the adjacent active layers,
the first buffer layers are provided between the active layers and the detection electrodes, and are provided so as to be separated from one another on a per detection electrode basis, and
the first buffer layers each include a plurality of zinc oxide nanoparticles and a zinc acetate layer provided in a space among the zinc oxide nanoparticles.
