Optical adhesive sheet and optical film with adhesive layer

The invention relates to an optical adhesive sheet and an optical film with an adhesive layer. The present invention provides an optical adhesive sheet suitable for ensuring the step absorbability of an end portion, and an optical film with an adhesive layer having such an optical adhesive sheet as an adhesive layer. This adhesive sheet (10) is an optical adhesive sheet having a main region section (11) and a soft end section (12) that is softer than the main region section (11). The ratio of the second press-fit elastic modulus of the soft end portion (12) at 25 DEG C to the first press-fit elastic modulus of the main region portion (11) at 25 DEG C is 0.85 or less. 本发明涉及光学粘合片和带有粘合剂层的光学膜。本发明提供一种适合于确保端部的高差吸收性的光学粘合片和具有这样的光学粘合片作为粘合剂层的带有粘合剂层的光学膜。本发明的粘合片(10)为具有主区域部(11)和比该主区域部(11)软的软质端部(12)的光学粘合片。软质端部(12)的25℃下的第二压入弹性模量相对于主区域部(11)的25℃下的第一压入弹性模量的比率为0.85以下。
