Abstract:
Provided is a laminate and an anti-reflection structure that can be thinned, are excellent in anti-reflection performance and can keep reflection chromaticity neutral.
In the laminate according to the present disclosure, a part of a light shielding film has a non-light shielding portion without a light shielding film; an anti-reflection structure is formed in the non-light shielding portion through an adhesion layer, and a fine uneven structure has an uneven period that is equal to or less than a wavelength of visible light; and a color difference (ΔE) between a reflected light by the light shielding film and a reflected light by the anti-reflection structure expressed in the formula shown below is equal to or less than 1.5. ΔE=√{square root over ((a1−a2)2+(b1−b2)2)}
