Abstract
According to one embodiment, provided are a first photoelectric conversion layer provided for a first wavelength band, a second photoelectric conversion layer provided for a second wavelength band, and a color separation element adapted to separate an incident light into a transmission light including the first wavelength band and a reflection light including the second wavelength band, wherein an angle of incidence of the incident light with respect to a reflection surface of the color separation element is set so that a vertically polarized light and a horizontally polarized light are included in the reflection light.
