Abstract
A transparent shock-absorbing laminate to be formed on a glass substrate for a display panel having a fracture strength such that it is fractured by a falling ball impact (drop height: 1.5 m; ball weight: 510 g) corresponding to 79,000 N, the transparent shock-absorbing laminate comprising a shatterproof layer having a shearing modulus of 2×108 Pa or more, at least two fracture-proof layers having a shearing modulus ranging from 1×104 to 2×108 Pa, each having different modulus, and a transparent pressure-sensitive adhesive layer.
