1. A solid-state imaging device, comprising:
a semiconductor substrate that including a photodiode; a color filter on a first surface of the semiconductor substrate in alignment with the photodiode, the color filter transmitting light within a predetermined wavelength band; a first reflection layer on the color filter, the first reflection layer including a concave curved surface; a supporting layer on; on the concave curved surface of the first reflection layer, the supporting layer being substantially transparent to light within the predetermined wavelength band; a second reflection layer on the supporting layer at a position corresponding to a focal point of the concave curved surface of the first reflection layer for light having a wavelength within the predetermined wavelength band of the color filter; a planarization layer on the second reflection layer and the first reflection layer; and a microlens on the planarization layer, wherein the supporting layer and the planarization layer are formed of a same resin material, and the first reflection layer and the second reflection layer are made of materials that have a refractive index higher than a refractive index of the resin material. |
