Abstract: An optical film, display module, and display screen, wherein the optical film comprises a main body, multiple microstructures, and an opaque layer. The microstructures are positioned on one side of the main body, and these microstructures are protruding arcuate structures. The opaque layer is affixed to the main body and is set opposite the microstructures on the other side of the main body, the opaque layer includes multiple apertures. Wherein, the center point of the apertures overlaps with the center point of the microstructures on a projection plane. Wherein, the equivalent diameter of the apertures divided by the equivalent diameter of the microstructures is less than or equal to 0.3, the equivalent diameter of the microstructures divided by the thickness of the main body is less than or equal to 1.3, and greater than or equal to 0.7. Wherein, the opaque layer is oriented towards the light source. The beneficial effect is that it can produce better collimated light, further improving the performance of the display module.
