Abstract

The invention discloses an anti-reflective film and a production method thereof. The anti-reflective film comprises film basic materials and a low refractive index layer which is arranged on at least a layer of the film basic materials; the low refractive index layer comprises (a) fluorine-containing organic matters which contain acryloyl group and methylacryloyl and with an refractive index between 1.30 to 1.43, (b) two kinds of inorganic particles with different particle diameters, (c) organic solvent with a boiling point which is higher than 100 DEG C and organic solvent with a boiling point which is lower than 100 DEG C, (d) adhesive resign and coating liquid which is made of (e) silane coupling agent and (f) photoinitiator and at least a surface of the film basic materials is coated by the coating liquid to be solidified to form into the low refractive index layer. The production method of the anti-reflective film is simple in production technology and enabling the air void of the low refractive index layer to be higher and the refractive index to be lower due to dry at different gradient. The anti-reflective film has the advantages of being good in anti-reflective performance and good in scratch resistant performance and satisfying requirements such as the anti-reflective performance and the scratch resistant performance of image displaying device such as liquid crystal displays, plasma displays and electroluminescent displays.

Description

technical field [0001] The invention relates to an anti-reflection film and a preparation method thereof. Background technique [0002] In recent years, image display devices such as liquid crystal displays (LCDs), plasma displays (PDPs), and electroluminescence displays (ELDs) have been widely used in fields such as televisions and computers. When these displays are used outdoors or in places with bright light, the display has the problems of unclear graphic display and extremely poor visibility due to the reflection of external light on the surface of the display. In order to solve such problems, anti-reflective film is usually placed on the outermost layer of the display to use the principle of optical interference to reduce the reflectivity, thereby improving the picture quality. In addition, since the anti-reflection film is used on the outermost layer of the display device, it should also have good scratch resistance. [0003] The preparation of anti-reflection film ...
