Beschreibung
Zusammenfassung:	A backlight module and a display device are described. The backlight module includes a light source structure and at least one optical film. The light source structure is configured to generate light. The optical film is disposed above the light source structure and includes a main body and plural optical structures disposed on the main body. Each of the optical structures is a tapered structure. Each of the optical structures has plural side surfaces, and a portion of light generated by the light source structure is guided toward primary directions when passing through the side surfaces of the optical structures, and therefore the light generated by the light source structure is no longer concentrated on the top of each of the optical structures.
