Abstract: A backlight module includes a light guide plate and a prismatic reflective film. The prismatic reflective film is disposed on a surface of the light guide plate opposite to a light exit surface of the light guide plate. A surface of the reflective film proximate to the light guide plate is provided with a plurality of protruding structures thereon. The plurality of protruding structures extending in a first direction. Tops of at least two of the plurality of protruding structures are uneven.
