Abstract:
1. A solid-state imaging device comprising a color filter including a group of dielectric layers, said color filter having high-refractive-index-material films and low-refractive-index-material films, said high-refractive-index-material films and said low-refractive-index-material films being n films and (n−1) films, respectively, which are laminated alternately, and n being an integer equal to or larger than 4, wherein said color filter includes at least a red-transmission filter, a green-transmission filter, and a blue-transmission filter, said group of dielectric layers is common to said red-transmission filter, said green-transmission filter, and said blue-transmission filter and includes two of said high-refractive-index-material films and one of said low-refractive-index-material films, the one of said low-refractive-index-material films being positioned between and in contact with the two of said high-refractive-index-material films, and in said red-transmission filter, a first one of said low-refractive-index-material films and a second one of said low-refractive-index-material films, which are not included in said group of dielectric layers, have a thickness different from each other.
