Abstract

The disclosure relates to a protective tape and a display device including the same. The protective tape includes a polymer film and an adhesive layer disposed on the polymer film. The adhesive layerhas a storage modulus at -20 DEG 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.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2019-0004672 filed on January 14, 2019, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] Exemplary embodiments of the present invention relate generally to a protective tape and a display device including the same, and more particularly, to a protective tape used in a flexible display device and a display device including the same. Background technique [0004] The display device displays various images on a display screen to provide information to a user. Typically, a display device displays information on a designated screen. Recently, flexible display devices including foldable or bendable flexible display panels are being developed. Unlike rigid display devices, flexible display devices can be folded, rolled or bent. A flexible display device whose shape can be vario...
