Abstract: Provided is an image sensor including: a substrate including a first pixel domain and a second pixel domain that are adjacent to each other in a first direction, the first pixel domain including first pixels and the second pixel domain including second pixels; a first color filter provided on a first surface of the substrate and vertically overlapping the first pixels; a first microlens provided on the first color filter and each of the first pixels; and a second microlens provided on the first surface of the substrate and vertically overlapping at least a portion of each of the second pixels, wherein a second refractive index of the second microlens is greater than a first refractive index of the first microlens, and wherein a level difference between an uppermost part of the first microlens and an uppermost part of the second microlens is within about 2% of a maximum height of the first microlens.
