A manufacturing method of a display device includes: forming, in a resin layer including a display area where a plurality of lower electrodes is formed and a peripheral area surrounding the display area, a band-like groove which divides the resin layer in a form of surrounding the display area; forming an organic electroluminescence layer including a light emitting layer, on the resin layer and inside the band-like groove in such a way as to be placed on the plurality of lower electrodes; irradiating the organic electroluminescence layer with a pulse laser and thus eliminating the organic electroluminescence layer in such a way that a part of the organic electroluminescence layer is left in a shape of an island at least on a bottom surface of the band-like groove and that the bottom surface of the band-like groove is continuously exposed in the form of surrounding the display area.

Display device

A display device includes a pixel provided in each of a plurality of pixels; a common electrode provided commonly to the plurality of pixels; an organic layer provided between the pixel electrode and the common electrode; a first insulating layer provided on the common electrode; a common potential line provided below the organic layer in an area where the first insulating layer, the common electrode and the organic layer are provided in a stacked manner; a contact electrode provided in an opening running through the first insulating layer, the common electrode and the organic layer, the contact electrode being provided on the common potential line; and a second insulating layer covering the first insulating layer and the contact electrode.
