Title:
ANTIREFLECTIVE ARTICLE, IMAGE DISPLAY DEVICE, AND MOLD FOR MANUFACTURING ANTIREFLECTIVE ARTICLE
Document Type and Number:
WIPO Patent Application WO/2015/145830
Kind Code:
A1
Abstract:
This invention improves, relative to existing antireflective articles, the abrasion resistance and optical properties of an antireflective article that has a moth-eye structure. In said antireflective article, in which tiny protrusions are densely arrayed and the spacing between adjacent tiny protrusions is less than or equal to the shortest wavelength in the wavelength band of electromagnetic waves to prevent the reflection of, said tiny protrusions comprise multi-peak tiny protrusions that each have a plurality of apices and single-peak tiny protrusions that each have a single apex, and letting P, σ, and Nt represent the mean, standard deviation, and total sample size, respectively, of the distribution of distances between adjacent tiny protrusions, letting Ns1 represent the number of samples in which at least one of the two tiny protrusions between which the distance is measured is a multi-peak tiny protrusion and the distance therebetween lies within the range P±σ, i.e. differs from the mean by no more than the standard deviation, and letting Ns2 represent the number of samples in which at least one of the two tiny protrusions between which the distance is measured is a multi-peak tiny protrusion and the distance therebetween lies outside the range P±σ, the ratio Ns1/Nt is greater than the ratio Ns2/Nt.
