Abstract
A solid-state imaging device includes a color filter on a substrate formed from a colored transparent material having a pigment with specified spectral transmissivity characteristics. The color filter possesses a plurality of spectral transmissivity characteristics in one layer. The distance from the color filter to the light sensing parts of the substrate is relatively uniform for all of the filter regions. This reduces flicker and other image characteristics defects. Since the device is not a laminate structure, cracks in the color filter due to thermal impact are reduced, and reliability is enhanced.
