Abstract: An image sensor includes: a first substrate including: a first side, a second side, a pixel array region, and an edge region; and a micro lens array on the second side, which includes micro lenses. Each of the micro lenses includes a first lens layer and a second lens layer on the first lens layer. A second mean curvature radius of the second lens layer is smaller than a first mean curvature radius of the first lens layer. A first eccentric degree of the second lens layer on an edge of the pixel array region is greater than a second eccentric degree of the second lens layer at a center of the pixel array region.
