Document Type and Number:
WIPO Patent Application WO/2022/244558
Kind Code:
A1
Abstract:
The present invention provides an adhesive sheet having an adequate storage elastic modulus and improved durability. This adhesive sheet has a 25°C storage elastic modulus G' of 0.4 MPa or greater. When a cross-section of the adhesive sheet is examined using a transmission electron microscope, the maximum diameter of a domain within a range that is 6 μm long by 6 μm wide is 170 nm or less. The adhesive sheet, e.g., includes two or more types of polymers.
