Abstract: Disclosed are a manufacturing method of an anti glare layer and a display panel. The method comprises: preparing a spray solution comprising sprayed particles, each having a shell structure; spraying the spray solution uniformly onto the glass substrate by a spraying device to form an arrangement structure on the glass substrate; spraying an acidic liquid on the arrangement structure to remove the shell structures of the sprayed particles each having the shell structure to form gaps among the spray particles; implementing an annealing treatment to the sprayed particles to form the anti glare layer. Thus, the light diffraction effect can be reduce or even eliminated to improve the picture quality of the display for promoting the comfort of the user viewing.

Abstract: Method for treating antireflection coatings on an optical substrate (17) involves a stage for carrying out the physical vacuum-deposit of a fluorinated polymer-containing layer having a low refractive index and is characterized in that the stage includes in deposing a silicium or magnesium fluoride/fluorinated polymer hybrid layer (21d) by simultaneous vacuum evaporation of silicium or magnesium fluoride and the fluorinated polymer, In a preferred embodiment, the fluorinated polymer is embodied in the form of a polymer or tetrafluorethylen polymer and the components are evaporated by a Joule effect or by electron bombardment. The method is advantageously used for improving the adherence of a low refractive index layer to a subjacent layer of a pile of antireflection coatings which is deposited on any optical substrate or the inventive substrate. The substrate produced by the method and a device for carrying out the method are also disclosed.
