AI Technical Summary

Technical Problem

Existing anti-glare laminates used in foldable or rollable image display devices suffer from insufficient bending resistance and flexibility, particularly when an acrylic resin substrate is employed, leading to cracks and reduced performance.

Method used

The anti-glare laminate is designed with a resin layer containing first particles with an average diameter of 0.5 μm or more, where 70% or more of these particles are positioned in a specific region, and the substrate surface has an average inclination angle of 5.0 to 20.0 degrees and an arithmetic mean height of 0.10 to 0.40 μm, enhancing both pencil hardness and bending resistance.

Benefits of technology

The laminate improves pencil hardness and bending resistance, allowing for greater design freedom in image display devices by maintaining flexibility and reducing the risk of cracking.

Abstract

To provide an anti-glare laminate with excellent pencil hardness and flexibility. [Solution] An anti-glare laminate having a resin layer on a substrate, wherein the resin layer contains first particles with an average particle diameter of 0.5 μm or more, and when the area from the center of the resin layer in the thickness direction toward the substrate is defined as the first region, and the area from the center of the resin layer in the thickness direction toward the substrate is defined as the second region, 70% or more of the number of first particles are present in the second region, and the anti-glare laminate satisfies either condition 1 or condition 2 below. <Condition 1> The average inclination angle of the surface of the substrate on the resin layer side is 5.0 degrees or more and 20.0 degrees or less. <Condition 2> The arithmetic mean height of the resin layer side surface of the substrate is 0.10 μm or more and 0.40 μm or less.
