Abstract: An optical film may include a first pattern layer having a first refractive index and including a base portion and a plurality of protrusions on the base portion x, and a second pattern layer disposed on the first pattern layer and having a second refractive index different from the first refractive index. Each of the protrusions may include n sub-protrusions (n is an integer of 2 or greater), which are stacked in a thickness direction of the base portion. Each of the n sub-protrusions may have a quadrilateral shape. A side surface of the protrusion defined by the n sub-protrusions may include at least one step portion. The optical film improves display quality of a display device in front and lateral directions.
