ABSTRACT:
The displacement amount of a color filter which is displaced with respect to an opening of a light-shielding film along the surface of a substrate increases as the distance from the substantial center of an image pickup region to the opening of the light-shielding film increases, and the height from the surface of the substrate to the substantial center in the direction of thickness of the color filter increases. For this reason, whole light incident on the sensor of each pixel can pass through only a corresponding color filter and also pass through the entire thickness of the color filter. Even when the thickness or height of the color filter changes in units of pixels, a high-quality image having no color irregularity can be obtained.
