摘要： The present invention relates to a photocurable adhesive film and a preparation method thereof, and provides an adhesive film having excellent peeling adhesion and creep resistance at both room temperature and high temperature and a low modulus at a low temperature of −20° C. by using an acrylic monomer having a specific structure in a specific content range. Furthermore, since the adhesive film of the present invention may provide folding reliability and stability of a display device, the adhesive film can be usefully applied as an adhesive of a display device, particularly, a foldable display device field.
