- the AR film or the LR film 112 shown in FIG. 17 has high surface resistance, it is difficult to obtain antiglare properties and the reflectance is not sufficiently reduced. Moreover, there is a feature that the reflected light has wavelength dependency, and there is a possibility that coloring due to the reflected light occurs. In particular, since the LR film is designed to preferentially reduce the reflectance seen from the front, the viewing angle dependency is particularly strong, and light from an oblique direction is almost regularly reflected.
- the moth-eye film 113 shown in FIG. 18 since most of the light is transmitted through the surface of the substrate 111, an excellent low reflectance can be obtained. Moreover, since the viewing angle dependence of reflected light is very small, there is little coloring. However, the surface of the moth-eye film 113 has an uneven structure, and sufficient surface resistance may not be obtained depending on the shape or size of each protrusion.
