An image sensing device for minimizing light reflected from a light shielding layer is disclosed. The image sensing device includes a semiconductor layer formed to include an active pixel region and an optical black pixel region, a light shielding layer located at the optical black pixel region formed over the semiconductor layer, a first color filter layer located at the active pixel region formed over the semiconductor layer, and a second color filter layer located over the light shielding layer. Each of the first and second color filter layers includes at least one first color filter, at least one second color filter, and at least one third color filter. In the first color filter layer, the first color filter, the second color filter, and the third color filter are arranged in the same layer. In the second color filter layer, the first color filter and the second color filter are arranged in the same layer whereas the third color filter is formed in another layer different from the layer of the first and second color filters.
