Abstract
A solid-state imaging device, for reduction of reflection of incident light at a sidewall surface of a light blocking layer of each phase difference detection pixel, includes: a normal pixel for generating a pixel signal; and a phase difference detection pixel for generating a phase difference signal for image plane phase difference AF. In this solid-state imaging device, the normal pixel and the phase difference detection pixel each include a photoelectric conversion layer and a lens for gathering incident light onto the photoelectric conversion layer, the phase difference detection pixel includes a light blocking layer having an apertural portion with an aperture deviating from the optical axis of the lens, and an antireflection portion that prevents reflection of the incident light gathered by the lens unit is formed on the light blocking layer. The present disclosure can be applied to back-illuminated CISs.
