Organic photodiode and method for manufacturing the organic photodiode

A manufacturing method of organic photodiode, being a method for manufacturing an organic photodiode comprising a pair of electrodes disposed oppositely to each other, a substrate forming one electrode of the pair of electrodes, a plurality of light receiving parts as layers of light absorbing composition disposed in a gap of the pair of electrodes, and partition walls formed in a gap of the pair of electrodes for insulating between the pair of electrodes and insulating between the light receiving part and the other light receiving part, comprising:

• a first electrode forming process that forms the one electrode on the substrate, an insulating layer forming process that forms an insulating layer covering the one electrode and its surrounding, an ink solution applying process that applies an ink solution containing a solvent for dissolving the insulating layer and the light absorbing composition on the insulating layer at a position corresponding to the one electrode, a light receiving part forming process that forms the plurality of light receiving parts by evaporating the solvent in the ink solution after dissolving the insulating layer, forming a plurality of dissolved holes as spaces contacting with the one electrode, and filling the plurality of dissolved holes with the light absorbing composition of the ink solution, and a second electrode forming process that forms other electrode of the pair of electrodes on the plurality of light receiving parts.
