<P>PROBLEM TO BE SOLVED: To provide an optical film, and a backlight module and a liquid crystal display having the optical film. <P>SOLUTION: An optical film is used to constitute a backlight module by attaching the film to a light-incident surface of a light guide plate and cooperating with a plurality of side-light sources. A specially designed microstructure is formed on the optical film to deflect light beams generated by the plurality of side-light sources into the light guide plate. The optical film can decrease an area of a dark region generating after the beams are mixed in the light guide plate, increase an effective visual range of the display, decrease the number of the plurality of side-light sources, and achieve cost reduction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
