Abstract: An optical film includes a first pattern layer including a first base portion and first protruding portions disposed on the first base portion to be spaced apart from each other and having a first refractive index and a second pattern layer disposed on the first pattern layer and having a second refractive index. Each of the first protruding portions includes a first sub-protruding portion having a first width in a cross-section perpendicular to the first base portion, a second sub-protruding portion disposed between the first base portion and the first sub-protruding portion and having a width that increases from the first sub-protruding portion to the first base portion, and a third sub-protruding portion disposed on the first sub-protruding portion and having a width that decreases as a distance from the first sub-protruding portion increases.

Abstract: A photocurable composition including a fluorine-based polymeric monomer, a (meth)acrylate monomer, and a photoinitiator. An amount of the fluorine-based polymeric monomer is in a range of about 20 parts to less than 40 parts by weight based on 100 parts by weight of the photocurable composition.
