Abstract: A viewing angle widening film, a manufacturing method thereof, and a display device are provided. A first film layer of the viewing angle widening film includes protrusions spaced apart from each other and extended along a first direction. The protrusions include a first protrusion and a second protrusion arranged on a side of the first protrusion away from a flat layer, a surface of the second protrusion on a side away from the flat layer is an arc surface, and a diffusion effect of the second protrusion is weaker than that of the first protrusion.

Abstract: Provided are a wide-viewing-angle optical film, a manufacturing method of the wide-viewing-angle optical film, and a liquid crystal display device. The manufacturing method includes: providing a substrate and forming a first light-transmissive layer at one side of the substrate; performing light treatment on the first light-transmissive layer to form protrusions on a surface of the first light-transmissive layer; and forming a second light-transmissive layer on one side of the first light-transmissive layer away from the substrate, in which a refractive index of a material of the second light-transmissive layer is greater than a refractive index of a material of the first light-transmissive layer to obtain a wide-viewing-angle film including the first light-transmissive layer and the second light-transmissive layer stacked on each other.
