Abstract

A display device according to the present invention comprises a window, a display module disposed below the window, and a protective tape disposed on the back surface of the display module to protect the display module. The protective tape comprises an insulating base layer comprising a first region and a second region, an adhesive layer disposed between the insulating base layer and the back surface of the display module corresponding to at least the second region, and a step layer disposed on the first region of the insulating base layer. Here, the end of the protective tape extends beyond the end of the window, and the step layer and the insulating base layer do not have an integral shape with each other.
