Problems solved by technology

However, since this known anti-reflection film is completely stacked by silica gel particles, the mechanical strength of the film is only due to the molecular force (or Van der Waals force) between the silica gel particles. The mechanical strength and hardness of the reflective film are poor, resulting in poor abrasion resistance of the anti-reflective film, which cannot be used for reflective optical coating of flat-panel displays

Abstract

The invention supplies an anti-reflection coating compound, the film and the manufacture method. It has an initialization agent and an oxide containing gel containing a gel particle with polymizable function radical. The film is formed by the gel particle and has plural nanometer hole. It could induce FI containing function radical and sharply decrease the effective refractive index below 1.45 to make the reflection ratio below 3%. The anti-reflection film has excellent mechanical strength and rigidity.

Description

technical field [0001] The invention relates to a three-dimensional nano-hole film and a manufacturing method thereof, in particular to a three-dimensional nano-hole film with high mechanical strength and anti-reflection capability and a manufacturing method thereof. Background technique [0002] In the manufacturing process of display devices (for example: optical lenses, cathode ray displays, plasma displays, liquid crystal displays, or light-emitting diode displays), in order to prevent the image from being disturbed by glare or reflected light, the outermost layer of the display device ( For example, a transparent substrate of a liquid crystal display) is equipped with an anti-reflection layer. [0003] Anti-reflection optical films with a single-layer structure have gradually become the main research and development trend of anti-reflection technology due to their excellent processing convenience, high yield, high output, and low equipment cost. However, known fluorine...
