  • Publication number: 20050077826
    Abstract: An impact-resistance film for a flat display panel which is to prevent breakage and scattering of glass of the panel when panel receives an impact and which at the same time makes the weight reduction and thickness reduction possible, is presented. An impact-resistant film 30 for a flat display panel, which is an impact-resistant film to be bonded to a front glass 22 of a flat display panel main body 21 and which comprises a first layer 23 on the front glass side of the flat display panel, made of a transparent synthetic resin having a shear modulus of from 1×103 Pa to 1×106 Pa, a second layer 24 on the viewer's side of the first layer, made of a transparent synthetic resin having a shear modulus of at least 1×108 Pa, and a third layer 25 on the viewer's side of the second layer, made of a transparent synthetic resin having a shear modulus of at least 1×106 Pa and less than 1×108 Pa.
