Document Type and Number:
Japanese Patent JP2023121121
Kind Code:
A
Abstract:
To provide a double-sided adhesive sheet by which, in a situation where constituent optical members of a display device having a touch panel are equipped with metallic electrically conductive parts, ion migration at the metallic electrically conductive parts can be inhibited when the optical members are pasted together, and changes of a resistance value due to a hygrothermal environment and ultraviolet rays can be inhibited.SOLUTION: Provided are: a double-sided adhesive sheet for pasting together a first adherend and a second adherend, both of which are constituent optical members of a display device having a touch panel, where the first adherend and/or the second adherend has electrically conductive parts, and where the adhesive sheet has a water vapor transmission rate of 400 g/m2/24 h or less, a sulfur content of 50 mg/kg or less, and a spectral transmittance of 30% or less at the wavelength of 380 nm; a laminate; and a method for manufacturing the laminate.SELECTED DRAWING: Figure 1
