Abstract: Disclosed is an image sensor including first and second pixels adjacent along a first direction, a first micro lens disposed on the first and second pixels, a first pixel isolation structure disposed outside the first and second pixels and penetrating from a first surface of a substrate to a second surface of the substrate opposite the first surface of the substrate, and a first floating diffusion region disposed at the first pixel and the second pixel and adjacent to the first surface of the substrate. The first floating diffusion region may not overlap the first pixel isolation structure along a height direction perpendicular to the first and second surfaces of the substrate, and the first floating diffusion region between the first pixel and the second pixel may be disposed at a position corresponding to a center portion of the first micro lens along an optical axis direction.
