An image sensor includes a substrate, a pixel isolation pattern in the substrate and defining unit pixel regions in the substrate, color filters on the substrate and corresponding to the unit pixel regions, respectively, a low-refractive index pattern between adjacent color filters of the color filters to at least partially isolate the adjacent color filters from direct contact with each other, an insulating structure between the substrate and the color filters, and a light blocking pattern vertically overlapping with the pixel isolation pattern. The light blocking pattern is within the insulating structure and is isolated from direct contact with the low-refractive index pattern.
