Zusammenfassung:The present application provides an adhesive layer comprising at least first and second regions having respectively different physical properties, wherein a difference in physical properties, such as modulus or creep strain, between the regions is maintained to be relatively large, and a difference in physical properties, such as peel strength or recovery rate, between the regions is maintained to be relatively small. La présente invention concerne une couche adhésive comprenant au moins des première et seconde régions ayant respectivement des propriétés physiques différentes, une différence de propriétés physiques, tel que le module ou la contrainte de fluage, entre les régions est maintenue pour être relativement grande, et une différence de propriétés physiques, telle qu'une résistance au pelage ou un taux de récupération, entre les régions est maintenue pour être relativement petite. 본 출원에서는, 서로 물성이 다른 제 1 및 제 2 영역을 적어도 포함하는 점착제층으로서, 탄성률이나 크리프 변형율(creep strain)와 같이 물성의 영역간의 차이는 영역별로 상대적으로 크게 유지되고, 박리력이나 회복률과 같이 물성의 영역간 차이는 상대적으로 적게 유지되는 점착제층을 제공한다.
