Abstract
A solid-state imaging device including a plurality of pixels arranged two-dimensionally, wherein each of the pixels has at least a planarizing film formed on the upper side of a photoelectric conversion element, a filter formed on the upper side of the planarizing film, and a microlens formed on the upper side of the filter. The filter of some of the pixels is a color filter permitting transmission therethrough of light of a predetermined color component, whereas the filter of other pixels is a white filter permitting transmission therethrough of light in the whole visible spectral range. The refractive indices of the white filter, the microlens and the planarizing film have the following relationship: (Refractive index of white filter)≧(Refractive index of microlens)>(Refractive index of planarizing film).
