Abstract
A backlight module comprises a light transmissive substrate, an optical film, and at least one light source. In this case, the optical film has a first surface and a second surface opposite to the first surface. The first surface of the optical film is connected to the transparent surface, and the second surface of the optical film has at least one fresnel area. The light source is disposed at one side of the light transmissive substrate.
