Abstract: An infrared transmission photosensitive resin composition includes (A) a pigment dispersion composition including a coloring agent (a1); (B) an alkaline soluble resin; (C) a photo-polymerizable compound; (D) a photo-polymerization initiator; and (E) a solvent, wherein the coloring agent (a1) includes a blue pigment, a red pigment and a yellow pigment. Thereby, the infrared transmission photosensitive resin composition may form an infrared transmission pixel which exhibits a high transmittance in an infrared region while having a very low transmittance in a visible light region, so as to be used in an image sensor for obtaining an image having excellent image quality at a place where the quantity of light is insufficient.
