Abstract: A fingerprint recognition optical film which transmits an infrared ray (IR) is introduced. The fingerprint recognition optical film may include a base film and a lens pattern layer including a plurality of lenses attached to one surface of the base film. Here, the plurality of lenses in the lens pattern layer are parallelly arranged with a predetermined distance and a flat pattern portion is formed among the lenses to transmit the infrared ray wherein a protrusion direction of the plurality of lenses is arranged to face to a light source.
