A display device includes a non-display area adjacent a display area, a thin film transistor, a display element, a thin film encapsulation layer, an organic insulating layer, a power voltage line, and a protective layer. The thin film transistor is on the display area and is connected to the display element. The thin film encapsulation layer covers the display element. The organic insulating layer is between the thin film transistor and display element and extends to the non-display area. The organic insulating layer includes a central portion corresponding to the display area, an outer portion surrounding the central portion, and a division region dividing the central portion and the outer portion and surrounding the display area. The power voltage line is in the non-display area and includes a portion corresponding to the division region. The protective layer covers an upper surface of the power voltage line in the division region.
