Abstract
A solid-state image pickup device includes photoelectric conversion parts formed on an image pickup surface of a substrate, where each photoelectric conversion part generates a signal charge by receiving incident light on a light reception surface thereof, and color filters formed on an image-pickup surface of the substrate, where each color filter allows the incident light to be colored by passing through. The photoelectric conversion parts are aligned in first and second directions and include first to third color filters. A surface on which the first color filter and the second color filter are laminated in the first direction is larger than a surface on which the first color filter and the third color filter are laminated in the second direction.
