ADHESIVE FILM, OPTICAL MEMBER INCLUDING THE SAME, AND OPTICAL DISPLAY INCLUDING THE SAME

An adhesive film has a glass transition temperature of about −10° C. or less. The adhesive film includes a first region and a second region, the second region being coplanar with the first region. The second region has a higher modulus than the first region at about −20° C. The first region has a mo...

Zusammenfassung:An adhesive film has a glass transition temperature of about −10° C. or less. The adhesive film includes a first region and a second region, the second region being coplanar with the first region. The second region has a higher modulus than the first region at about −20° C. The first region has a modulus of about 0.01 MPa to about 1.5 MPa at about −20° C. The second region has a modulus of about 0.1 MPa to about 50 MPa at about −20° C.
