Abstract: A protective tape including a polymer film and an adhesive layer disposed on the polymer film. The adhesive layer has a storage modulus at −20° C. of 30 KPa to 100 KPa, and a creep value of 100% to 800% when a load of 3 N is maintained for 2 hours at room temperature. Thus, the protective tape is capable of maintaining a high adhesion value with respect to a display device while minimizing damage to the adhesive layer.
