Abstract: An image sensor comprising a substrate having first and second surfaces opposite to each other, a pixel isolation section that penetrates the substrate and separates a plurality of pixels constituting first, second, and third pixel groups, each of the first, second, and third pixel groups including pixels that are arranged in n columns and m rows, a light-shield grid on the first surface and overlapping the pixel isolation section, and a light modulator on the first surface and overlapping the pixel isolation section on a center of each of the first, second, and third pixel groups. The light-shield grid has a first width in a first direction. The light modulator has a second width greater than the first width in the first direction.
