Abstract: Disclosed is a display device which is capable of preventing an encapsulation film from being formed in a scribing line, and a method for manufacturing the same. The display device includes a substrate having a display area provided with pixels, a non-display area surrounding the display area, an encapsulation film including an inorganic film which covers the display area, and a buffer layer. The buffer layer is provided at a predetermined interval from the display area in the non-display area and is brought into contact with the edge of the inorganic film.
