Abstract: A display device includes a display module, and a window which is disposed on the display module and in which a first non-folding region, a folding region, and a second non-folding region are sequentially defined in a first direction, wherein the window includes a base layer, a first hard coating layer disposed on an upper surface of the base layer, and a second hard coating layer disposed on a lower surface of the base layer, and the second hard coating layer includes a first portion overlapping the first non-folding region and the second non-folding region of the window, and a second portion overlapping the folding region of the window and having a hardness lower than a hardness of the first portion. Therefore, it is possible to provide a display device having desired surface hardness, impact resistance, and bending properties.
