ADHESIVE SHEET AND METHOD OF MANUFACTURING STACKED STRUCTURE USING THE SAME

摘要

The present invention relates to an adhesive sheet which is formed by an adhesive composition comprising: an acrylic compound; a photoreactive monomer; and a photopolymerization initiator. Storage modulus is 0.05 MPa or more at 80°C after primary photo-curing for forming the adhesive sheet, double curvature measured at 25°C after the primary photo-curing is 4.0% or more, and the difference between the stress relaxation ratio measured after second photo-curing which selectively activates the photoreactive monomer and the stress relaxation ratio measured after the primary photo-curing is 0.2 or more.
