Optical film structure, manufacturing method thereof and display device

An optical film structure, comprising:

• a substrate layer, having a first surface and a second surface opposite to each other, and
• a micro-lens array layer, provided on at least one of the first surface and the second surface, and comprising a plurality of micro-lenses arranged in an array, wherein edges of the adjacent micro-lenses abut on each other;
• wherein:
• the micro-lens array layer is arranged on the first surface;
• the optical film structure further comprises a diffusion layer provided on at least one of a surface of the micro-lens array layer away from the substrate layer and the second surface;
• and the diffusion layer comprises a plurality of uneven microstructures;
• or,
• the micro-lens array layer is provided on each of the first surface and the second surface;
• the optical film structure further comprises a diffusion layer provided on a surface of the micro-lens array layer away from the substrate layer;
• and the diffusion layer comprises a plurality of uneven microstructures.
