An optical film is disclosed. The optical film may include a first base film, and a diffusion lens layer disposed on one surface of the first base film and including a plurality of square pyramid-shaped lenses. Edges meeting at vertices of the plurality of square pyramid-shaped lenses may be curved lines. Among the plurality of square pyramid-shaped lenses, one surface of a first square pyramid-shaped lens may meet one surface of a second square pyramid-shaped lens to form a boundary line, and the one surface of the first square pyramid-shaped lens and the one surface of the second square pyramid-shaped lens may be symmetrical with respect to the boundary line as an axis.

Optical film

A diffusion sheet includes a first base film, a second base film, and a shielding layer placed between the first base film and the second base film. In this case, the shielding layer includes an air gap and a pattern.

Diffusion sheet and a backlight unit including the diffusion sheet

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.
