Abstract: Provided is a solid-state imaging element configured to automatically extend dynamic range for each unit pixel. A solid-state imaging element includes, for a unit pixel, a first photoelectric conversion element, a first accumulation portion that accumulates electric charge obtained by photoelectric conversion by the first photoelectric conversion element, and a first film that is electrically connected to the first accumulation portion and has an optical characteristic changing according to applied voltage. Furthermore, the unit pixel of the solid-state imaging element can further include a first transfer transistor that transfers electric charge obtained by photoelectric conversion by the photoelectric conversion element to the first accumulation portion, an amplification transistor that is electrically connected to the first accumulation portion, and a selection transistor that is electrically connected to the amplification transistor.

Abstract: The present technology relates to an imaging element, a method of manufacturing the same, and an electronic appliance capable of reducing false signal output caused by reflected light of incident light. An imaging element includes: a semiconductor substrate including a photoelectric conversion unit for each pixel, the photoelectric conversion unit photoelectrically converting incident light; a color filter layer that is formed on the semiconductor substrate and that passes the incident light of a predetermined wavelength; a light-shielding wall that is formed at a pixel boundary on the semiconductor substrate so as to have a height greater than a height of the color filter layer; and a protective substrate that is disposed via a seal resin and that protects an upper-surface side of the color filter layer. The present technology can be applied to, for example, an imaging element having a CSP structure and the like.
