A method for manufacturing a light guide includes providing a roll unit, enclosing a metallic film around the roll unit wherein the metallic film has a plurality of micro-protrusions, driving a light guide film to pass through the roll unit to form a plurality micro-indentations on the light guide film, and cutting the light guide film to have a determined size to form a light guide. Thus, the light guide is made by hot rolling so that the light guide is made easily and quickly. In addition, only the surface of the light guide film is heated and softened so that after the light guide film is hot rolled by the roll unit, the light guide film is cooled and solidified quickly to prevent the light guide film from being deformed due to an excessive heat.
