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: A display panel includes a thin film transistor (TFT) array substrate, an opposite substrate, and a liquid crystal layer disposed between the TFT array substrate and the opposite substrate. The TFT array substrate includes a first substrate. The opposite substrate includes a second substrate. The display panel further includes a first viewing-angle improving layer disposed between the first substrate and the second substrate. The first viewing-angle improving layer adjoins one film layer on the first substrate or the second substrate. The first viewing-angle improving layer is disposed between the first substrate and the second substrate so that the first viewing-angle improving layer can be a stacked part manufactured integratedly with other film layers of the display panel. Thus, manufacture of the first viewing-angle improving layer can overcome a size limitation of a mold in a nanoimprinting technology, effectively improving a large-viewing-angle-display effect of a large-size display panel.
