Backlight module and display device

A backlight module, comprising:

• a surface light source;
• an optical film, disposed on an emitting side of the surface light source, wherein the optical film is a louver film with multiple blocking sections spaced along a first direction and multiple light-transmitting sections located between adjacent blocking sections;
• and
• a light control film, comprising a first reference surface and multiple first optical structures positioned on the first reference surface, wherein the first reference surface is located on one side of the light control film facing away from the optical film, each of said first optical structures comprises a first optical surface and a second optical surface, wherein the first optical surface and the second optical surface are arranged along the first direction, the first optical surface and the first reference surface form a first included angle θ1, the second optical surface and the first reference surface form a second included angle θ2, the first included angle θ1 is an acute angle, and the first included angle θ1 is smaller than the second included angle θ2.
