密着性にも問題があった。However, the conventional antiglare film has a problem that the light amount of 10% to 20% of the total light transmission amount is lost. In addition, there is a problem that the display quality is deteriorated due to white blur due to irregular reflection on the surface. As the antireflection coating, it is known to deposit a low refractive index material such as magnesium fluoride, and it is put to practical use in spectacle lenses and the like. However, in the vapor deposition method, there is a problem in the film formation homogeneity on the entire surface in various shapes, and since an expensive vacuum device that does not have high throughput is required, it is extremely expensive for applications that require a large area. There was a problem that it would become something like. There was also a problem with the adhesion to the resin.

成される。The above object is achieved by forming a fluorine-containing polymer layer on the light-scattering layer in the antiglare film having the light-scattering layer. The fluorine-containing polymer constituting it must be soluble in a solvent and have a crosslinkable functional group. Thereby, by coating the fluorine-containing polymer solution on the light-scattering layer, the fluorine-containing polymer layer can be formed and further cured by any method of heating, ultraviolet ray irradiation, electron beam irradiation, and ozone exposure. Thus, it becomes possible to manufacture an antiglare film. Further, in the display device, the above object is achieved by providing an antiglare film in which a fluorine-containing polymer layer is formed on the light scattering layer, at the outermost part of the display surface.

はない。Recently, solvent-soluble fluorine-containing polymers have been obtained. Maintaining the low refractive index peculiar to fluorine-containing polymers,
Moreover, since it is soluble in a solvent, it is possible to easily obtain a thin film having no pinhole and excellent in visible light transmittance by coating. Depending on the material, an astonishing characteristic with a refractive index of 1.29 can be obtained. When used as an antireflection coating, a certain degree of effect can be obtained if the refractive index is 1.40 or less, which is equivalent to that of magnesium fluoride. The solvent that dissolves the solvent-soluble fluorine-containing polymer is an inert fluorine-based solvent and does not violate the resin of the film material that is generally used.

硬化させなければならない。The film thickness that is usually used to obtain the antireflection effect is obtained by an integer multiple of (wavelength of light) ÷ 4 ÷ (refractive index of film). There is almost no light attenuation due to the absorption of the film. Even if the substrate surface is not smooth, a uniform film thickness can be secured by using the coating method. In general, a fluorine-containing polymer has a weak surface interaction due to weak intermolecular interaction, and thus needs to be three-dimensionally crosslinked. If it is three-dimensionally crosslinked in the raw material stage, it becomes difficult to dissolve it, so it must be reacted and cured after coating.
