Document Type and Number:
WIPO Patent Application WO/2022/181656
Kind Code:
A1
Abstract:
The present disclosure addresses the problem of providing an adhesive-layer-equipped elastic sheet with which it is possible to suppress the occurrence of wrinkling in a curved section with respect to a bend at which the bending radius of a display, etc., is very small. This adhesive-layer-equipped elastic sheet (1) comprises: an elastic body layer (2) in which the tensile elasticity at 20°C is at least 80 MPa and less than 1,500 MPa, and in which the tensile elasticity at 85°C is at least 40 MPa and less than 1,000 MPa; and an adhesive layer (3) overlapping the elastic body layer (2). The thickness of the adhesive layer (3) is 2-15 μm. The adhesive force of the adhesive layer (3) with respect to a polyethylene terephthalate film is at least 10 N/25 mm.
