[Prior Art] In recent years, the popularity of mobile terminals, notebook computers, and large-sized TVs has been remarkable. Since the group of people in these devices has an image display device (display device), it is required to have visibility (visibility) as the first function, but in actual use, since the background is reflected in the image display portion (face), the contrast It is difficult to see that there are many situations such as falling. Therefore, the industry has tried to suppress the surface reflection of the surface which is the cause of the decrease in visibility. As a method of suppressing the surface reflection, it is usually implemented on the surface of the display device to form irregularities, and the image is dispersed by the scattering of light to make the wheel anti-glare Processing (Japanese Patent Laid-Open Publication No. 2010-256851). However, since the anti-glare treatment is formed by laminating an anti-glare layer containing inorganic particles such as ceria or organic particles such as styrene, acrylic or the like on the transparent film substrate, the resolution of the image is lowered. In order to solve this problem, a film having a degree of light on the surface is disclosed, and an antireflection treatment for reducing the reflectance by the interference effect of light is disclosed (Japanese Patent Laid-Open Publication No. 2010-286657). Further, it is disclosed that a fluorine-based resin or a polyoxymethylene-based resin is used for the antireflection treatment (Japanese Patent Laid-Open Publication No. 2010-243879).
