Abstract
The present invention provides an optical film comprising a substrate including a photoluminescent material and an adhesive layer formed on one surface of the substrate. The optical film according to the present invention can not only enhance the visibility of a laser pointer when the laser pointer is pointed on a display having the optical film adhered thereto, but also suppresses the generation of bubbles when adhered to an antiglare-treated display having fine asperities on its surface to prevent the deterioration of visibility, and can also have an excellent transmissive clarity and be easily attached and detached.
