Claim 15:
16. A method for manufacturing a display device, comprising the steps of:
forming a TFT layer onto a base substrate;
forming a light-emitting element onto the TFT layer, the light-emitting element forming a display region;
forming a sealing film over the light-emitting element;
forming a cut in a frame region by partly cutting the frame region and the display region, the frame region surrounding the display region; and
forming, in the frame region between the display region and the cut, a cut-peripheral wall along a boundary of the display region, the step of forming the cut-peripheral wall being performed before the step of forming the sealing film,
wherein the step of forming the sealing film includes
a step of forming a first inorganic insulating film over the light-emitting element,
a step of forming an organic film over the first inorganic insulating film through evaporation,
a step of ashing the organic film to form an organic buffer layer onto a surface of the cut-peripheral wall, and
a step of forming a second inorganic insulating film over the first inorganic insulating film and the organic buffer layer.
