Patent number: 8541858Abstract: A solid state imaging device includes: a first photoelectric conversion layer of an organic material; a second photoelectric conversion layer of an inorganic material; a third photoelectric conversion layer of an inorganic material; a first filter of an inorganic material; a second filter of an inorganic material. The first photoelectric conversion layer photoelectrically-converts a light of a first color. The first filter is disposed between the first photoelectric conversion layer and the second photoelectric conversion layer to selectively guide a light of a second color, out of a light that passed through the first photoelectric conversion layer, to the second photoelectric conversion layer. The second filter being disposed between the first photoelectric conversion layer and the third photoelectric conversion layer to selectively guide a light of a third color, out of the light that passed through the first photoelectric conversion layer, to the third photoelectric conversion layer.Type: GrantFiled: March 21, 2011Date of Patent: September 24, 2013Assignee: Kabushiki Kaisha ToshibaInventor: Koichi Kokubun
