  • Publication number: 20220190017
    Abstract: An image sensor in which a shading phenomenon is decreased and the quality is increased is provided. The image sensor includes a light-receiving region including a plurality of unit pixels. The image sensor further includes a first region with unit pixels adjacent to a center of the light-receiving region, and a second region with the unit pixels spaced apart from the center of the light-receiving region. In both regions, a plurality of color filters corresponding to the plurality of unit pixels is disposed on a first face of the substrate, as well as a grid pattern interposed between the plurality of color filters defining boundaries between the unit pixels. A width of the grid pattern in the second region is greater than a width of the grid pattern in the first region, thereby adjusting light receiving areas near the edge of the image sensor to correct for a shading phenomenon.
