A backlight module includes a light source, an optical film, and a light control film. The light control film has a first reference surface and a plurality of first optical structures disposed on the first reference surface. Each of the first optical structures has a first optical surface and a second optical surface. A first included angle is formed between the first optical surface and the first reference surface. A second included angle is formed between the second optical surface and the first reference surface. The first included angle is an acute angle and is smaller than the second included angle. Thereby, the light can be deflected to one side and the light output of the other side can be suppressed. This invention also provides a display device including the backlight module.
