Abstract: An image sensor includes a substrate including a first region and a second region surrounding the first region, a light sensing element in the substrate, a planarization layer on the light sensing element, a color filter array layer including color filters on the planarization layer on the first region of the substrate, a light blocking metal pattern on the planarization layer on the second region of the substrate, a dummy color filter layer on the light blocking metal pattern on a portion of the second region adjacent to the first region of the substrate, and microlens on the color filter array layer. Active pixels are in the first region, and optical black (OB) pixels are in the second region.
