Abstract: A viewing angle diffusion film and a display panel are provided, including a substrate and a plurality of refractive protrusions. Through arranging two adjacent refractive protrusions in a staggered layout with changes periodically in each column of refractive protrusions, that is, initial positions of each column of refractive protrusions are not on a same straight line, a Moire effect can thereby be reduced, improving a quality of the display panel.

Abstract: The present invention provides a viewing angle diffuser film and a display panel, including a base substrate and refractive protrusions. By setting space ratios of adjacent refractive protrusions in a first direction and a second direction, refraction directions of the viewing angle diffuser film can be controlled, and therefore light diffusion effects can be controlled. In the display panel of the present invention, the space ratios of the refractive protrusions in different directions are adjusted according to different usage scenarios to improve display brightness and reduce color shifts.

Abstract: Disclosed are a viewing angle adjustment film structure, a manufacturing method thereof, and a display device, including a base, an isotropic optical material layer, and a liquid crystal layer stacked in sequence. The isotropic optical material layer is provided with grooves, the liquid crystal layer fills the grooves, and light enters from the liquid crystal layer and then exits through the isotropic optical material layer. Director of liquid crystal molecules in the liquid crystal layer is changed according to an external applied voltage or a change of an electric field, so as to adjust a viewing angle of the light emitted from the isotropic optical material layer.
