IMAGING ELEMENT AND ELECTRONIC DEVICE

WIPO Patent Application WO/2020/022100

A1

The present technology relates to an imaging element and an electronic device that can acquire various pieces of information which pertains to a subject and includes polarization information. The present invention comprises: an organic photoelectric conversion film which has optical transparency, is oriented in a predetermined axial direction, and has stepped sections; an upper electrode disposed on a light incident surface side of the organic photoelectric conversion film; and a lower electrode disposed on an upper electrode-facing side of the organic photoelectric conversion film. Protrusions and recesses are formed on the light incident surface side of the organic photoelectric conversion film. An accumulation layer that accommodates charges converted by the organic photoelectric conversion film is provided between the organic photoelectric conversion film and the lower electrode, and formation of the stepped sections are determined depending on the presence or absence of the accumulation layer. The present technology can be applied to, for example, an imaging element that detects a polarization component in a predetermined direction.
