The optical recognition device includes a transparent substrate, a patterned infrared reflective film formed thereon, and an infrared anti-reflective film sheltering a gap in a recognition pattern of the patterned infrared reflective film, wherein the patterned infrared reflective film reflects the recognition pattern by reflection of infrared light and transmission of visible light. The invention also provides a display incorporating the optical recognition device.
