Abstract: An image sensor includes a first substrate including pixel regions, each of the pixel regions including a photoelectric conversion region, color filters on the pixel regions, the color filters on a first surface of the first substrate, micro lenses on the color filters, and a lens coating layer on the micro lenses. The lens coating layer includes a first coating layer and a second coating layer, the second coating layer is on the first coating layer, the first and second coating layers include a same material, and a density of the second coating layer is greater than a density of the first coating layer.
