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.
