An optical film having high reliability and a method for manufacturing the same are provided. The optical film includes a quantum dot layer, an upper protective layer and a lower protective layer. The upper protective layer is formed on a surface of the quantum dot layer. The lower protective layer is formed on another opposite surface of the quantum dot layer. The upper protective layer and the lower protective layer each include a bonding layer, a moisture and oxygen barrier layer, and a substrate layer located between the bonding layer and the moisture and oxygen barrier layer. The bonding layer is arranged proximate to the quantum dot layer and formed from an aqueous coating material. The moisture and oxygen barrier layer is arranged away from the quantum dot layer and includes an evaporated layer and an outer plastic layer formed on the evaporated layer.
