Abstract: 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.
