Abstract
(EN)
Provided is an adhesive film having excellent bendability and transparency. Also provided are a foldable device and a rollable device having excellent bendability. This adhesive film has a substrate layer and an adhesive layer, tan δ(0.7%) at a strain of 0.7% of the adhesive film measured in the tension mode of a viscoelasticity measurement device being 0.1 or less. This adhesive film has a substrate layer and an adhesive layer, the difference (tan δ(0.7%) – tan δ(0.1%)) between tan δ(0.7%) at a strain of 0.7% and tan δ(0.1%) at a strain of 0.1% of the adhesive film measured in the tension mode of a viscoelasticity measurement device being 0.05 or less.
