Title:
ANTIREFLECTION ARTICLE, IMAGE DISPLAY DEVICE, AND DIE FOR MANUFACTURING THE ANTIREFLECTION ARTICLE
Document Type and Number:
Japanese Patent JP2014209231
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an antireflection article related to a moth-eye structure that improves scratch resistance more than before and that improves an antireflection function.SOLUTION: An antireflection article is provided in which: very small protrusions are closely arranged; and the distance between the adjacent very small protrusions is equal to or lower than a minimum wavelength in a wavelength band of electromagnetic waves prevented from reflecting. The very small protrusions include multi-peak very small protrusions having a plurality of peaks and single-peak very small protrusions having single peaks. In the frequency distribution of the lengths D of line segments connecting each of the peaks of the multi-peak very small protrusions, an average value P is 30 nm≤P≤40 nm, and a standard deviation σ is 5 nm≤σ≤15 nm.
