A display device and a method of manufacturing the same are disclosed. In one aspect, the display device includes a display area configured to display an image and a bending area adjacent to the display area. The display device is bendable along the bending area; a flexible base substrate. A thin film transistor is disposed over the base substrate, and an insulation layer is disposed over the base substrate and covering the thin film transistor. The bending area includes a stress distribution region having opposing end portions and a central portion. Each of the opposing end portions has a width larger than the width of the central portion, and the width of each opposing end increases as a function of distance from the central portion.
