Abstract
An optical film is disclosed. The optical film is divided into a main body and two extending portions arranged along a second direction by two imaginary lines which are extended along a first direction and parallel to each other, wherein the second direction is substantially perpendicular to the first direction. The main body is located between the two extending portions. Each of the extending portions has an abutting edge. A first length W0 of the main body along the first direction is greater than a second length W1 of the abutting edge along the first direction.
