Abstract
Provided is an image sensor including a color separating lens array. The image sensor includes: a sensor substrate including a first pixel configured to sense light of a first wavelength and a second pixel configured to sense light of a second wavelength; a transparent spacer layer on the sensor substrate; and a color separating lens array on the spacer layer, wherein the color separating lens array condenses the light of the first wavelength toward the first pixel, and includes a first lens layer on the spacer layer, a second lens layer on the first lens layer, and an etch prevention layer between the first lens layer and the second lens layer.
