Title:
WINDOW BASE MATERIAL, MULTILAYER WINDOW, MULTILAYER WINDOW WITH ADHESIVE LAYER, AND DISPLAY DEVICE INCLUDING MULTILAYER WINDOW
Document Type and Number:
WIPO Patent Application WO/2023/153052
Kind Code:
A1
Abstract:
This window base material includes a structure in which glass and a resin film 2A are laminated. The maximum value of an impact load change determined in a pen drop test at 25°C is 13 N/ms or less. The product, M2A × T2A, of the mean value M2A of the tensile storage modulus in a 2-20 kHz frequency range and a temperature of 25°C of the resin film 2A and the thickness T2A of the resin film 2A satisfies 50 GPa·μm ≤ M2A × T2A ≤ 250 GPa·μm.
