Abstract

An optical film including a body and a plurality of first linear protrusions is provided. The body has a first surface and a second surface opposite thereto. The first linear protrusions are disposed on the first surface. Each of the first linear protrusions extends along a first direction. Each of the first linear protrusions has a first curviform ridge line away from the first surface wherein the first curviform ridge line is curved toward a fixed direction. A fictitious plan where the first curviform ridge line is located is not parallel to the first surface. The abovementioned optical film is not easy to be abraded.
