Problems solved by technology

Especially when the display device is used in a bright place, since a large amount of external light will be incident on the outermost surface of the display device, if the surface reflectance is not sufficiently reduced, the amount of reflected light will be lower than that of the display light emitted from the inside of the display device. The ratio of the amount of light will be too large to be clearly displayed

Embodiment approach 1

[0092] (1) Composition of anti-reflection structure

[0093] figure 1 It is a cross-sectional schematic diagram of the moth-eye structure of the antireflection structure according to the first embodiment. The antireflection structure according to Embodiment 1 has a transfer resin layer 11 on a base film 10 and has a concavo-convex structure (moth-eye structure) on the surface of the transfer resin layer 11 . The moth-eye structure is used to reduce reflection on the surface of the anti-reflection structure. The antireflection structure according to Embodiment 1 uses a film-like resin substrate including the base film 10 and the transfer resin layer 11 , and is therefore also called an antireflection film, a moth-eye sheet, or a moth-eye film. Using a moth-eye film can reduce the surface reflection of visible light in various substrates by placing it on a substrate (object to be reduced in surface reflection).

Abstract

The present invention provides: an antireflection structure capable of improving design characteristics by adjusting the reflective properties of a moth-eye structure; and a display device using this antireflection structure. This antireflection structure has: a resin base material having an uneven structure on the surface thereof that has a height from the floor to the peaks thereof that is no greater than the wavelength of visible light; and a resin layer covering at least part of the uneven structure. The resin layer covers the floor of the uneven structure more thickly than the peaks of the uneven structure.

Description

technical field [0001] The present invention relates to an antireflection structure and a display device. More specifically, it relates to an antireflection structure in which the surface reflectance is lowered by a concavo-convex structure provided on the surface, and a display device in which the surface reflectance is reduced using the antireflection structure. Background technique [0002] Conventionally, as a technique for reducing surface reflection, a light interference film formed by laminating layers with different refractive indices is known. In recent years, research on a moth-eye (moth's eye) structure, which is a concave-convex structure with a size smaller than the wavelength of visible light, is advancing as a technology capable of significantly reducing surface reflection compared to light interference films. [0003] The moth-eye structure is a concave-convex structure that is finer than the concave-convex structure formed on an anti-glare (AG: Anti Glare) ...
