US 2003/0176124 A1 · Laminate body and display device using the laminated body

Abstract

A laminate which can easily attain safety standards such as impact resistance, while cost reduction is aimed for, for example, when the laminate is provided on a display viewing surface, and a display apparatus using this laminate are provided. By using a filter for a display having a specified parameter and a specified thickness, the impact resistance is enhanced. By using the filter for the display containing a transparent adhesive layer having a specified Young's modulus and a specified thickness, the impact resistance is enhanced. By using the filter for the display containing a transparent resin layer having a specified Young's modulus and a specified thickness, the impact resistance is enhanced. By using the filter for the display containing an impact absorption layer having a specified penetration and a specified thickness, the impact resistance is enhanced.

Claims20

Dependent claims

A laminate comprising at least a transparent adhesive layer and a transparent resin layer and having a thickness of 3.5 mm or less, wherein the following relation is satisfied:

T/F≧200
in which T (μs) represents a period of time during from generation of impact stress to an appearance of a first peak and F (kN) represents impact stress at the time of the first peak in a stress-time curve at a ball drop impact test in which a steel ball having a weight in a range of from 530 g to 550 g is dropped from a height of 10 cm.

Dependencies are inferred from the claim text.
