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.

Fingerprint recognition optical film, and backlight unit and liquid crystal display device comprising the film optical

Disclosed is an optical film includes a first prism sheet including a plurality of first prisms arranged on one side of the first prism sheet, a second prism sheet including a plurality of second prisms arranged on one side of the second prism sheet, and a diffuser sheet including a plurality of first protrusions and a plurality of second protrusions arranged on one side of the diffuser sheet. The optical film is prepared to have a height of the first protrusions being greater than a height of the second protrusions. The optical film is further prepared that the first prism sheet, the second prism sheet and the diffuser sheet laminated where the first protrusions of the diffuser sheet is adhered to a side of the first prism sheet where no first prisms are arranged, and the first prisms of the first prism sheet are adhered to a side of the second prism sheet where no second prisms are arranged.
