A protective tape including a polymer film and an adhesive layer disposed on the polymer film. The adhesive layer has a storage modulus at &#x2212;20&#xb0; 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.

Protective tape and display device including the same

An electronic device includes a window having a modulus of about 55 GPa to about 80 GPa, an panel including an electronic element, and a plurality of adhesive layers between the window and the panel, wherein a sum of thicknesses of the adhesive layers is less than about 200 &#x3bc;m, wherein the adhesive layers include a first adhesive layer contacting the panel, and a second adhesive layer contacting the window, and wherein a thickness of the first adhesive layer is equal to or less than about &#xbd; of the sum of the thicknesses of the adhesive layers.

Electronic device

An organic light-emitting display apparatus including a substrate; a thin-film transistor (TFT) arranged on the substrate; a black matrix located between the substrate and the TFT; a pixel electrode, which is located between the substrate and the TFT and having edge portions covered by the black matrix; an insulation layer, which covers the TFT and opens the top surface of the pixel electrode; an organic emission layer, which is arranged on the pixel electrode; and a counter electrode, which is arranged on the organic emission layer.
