Abstract
An optical film for use in backlight module is provided. The optical provides quality luminance of a liquid crystal display (LCD) apparatus. The optical film assembly comprises a substrate with a polarization direction, in which the substrate has a first surface and a second surface opposing thereto. A first prismatic structure is formed on the first surface. The polarization direction of the substrate defines the first angle θ1 with respect to the configured direction of the first prismatic structure, in which 0°<θ1<180°.
