Abstract: An image sensor is disclosed. The image sensor may include a plurality of unit pixels, a color filter array provided on the plurality unit pixels, the color filter array including color filters, an anti-reflection layer disposed between the plurality of unit pixels and the color filter array, and a fence pattern including a lower portion buried in the anti-reflection layer and an upper portion separating the color filters from each other. A width of the upper portion of the fence pattern may be greater than a width of the lower portion.
