Abstract

A display device includes an active region, a pad region adjacent to the active region, a first peripheral region between the active region and the pad region, a second peripheral region outside the active region and spaced apart from the pad region, a base layer, a circuit layer on the base layer, a light-emitting element layer on the circuit layer and corresponding to the active region, a capping layer on the light-emitting element layer, a dam part extended along the active region and in the first peripheral region and the second peripheral region, and a protruding part outside the dam part in the second peripheral region and on the base layer.

Claims (27)

1 . A method for providing an electronic device, the method comprising:

providing a plurality of display panels removably disposed on a substrate;

providing a protective layer which includes a protective layer resin and is removably disposed on the display panels;

removing the protective layer from the display panels, to provide final display panels from which the protective layer is removed; and

providing a light control layer to each of the final display panels to provide a display device of the electronic device.

2 . The method of claim 1 , wherein the providing of the plurality of display panels comprises:

providing a base layer comprising an active region, a pad region adjacent to the active region, a first peripheral region between the active region and the pad region, and a second peripheral region which is outside the active region, adjacent to the first peripheral region and spaced apart from the pad region;

providing in order from the base layer, a circuit layer comprising a thin film transistor, an insulating layer and a light-emitting element layer; and

providing on the base layer, each of:

a dam part which extends along the active region, in the first peripheral region and the second peripheral region; and

a protruding part which is further from the active region than the dam part, in the second peripheral region.

3 . The method of claim 2 , wherein the providing the protective layer comprises providing the protective layer resin on each of the display panels, the protective layer resin having an outer edge furthest from the active region and corresponding to the protruding part which is further from the active region than the dam part.

4 . The method of claim 1 , wherein the protective layer resin comprises an acrylic resin.

5 . The method of claim 1 , wherein the providing the protective layer comprises:

providing the protective layer resin on each of the display panels, and

providing an ultraviolet light to the protective layer resin,

wherein the ultraviolet light has a center wavelength of about 365 nanometers to about 395 nanometers.

6 . The method of claim 1 , wherein the providing of the protective layer comprises:

providing the protective layer resin on each of the display panels;

first curing the protective layer resin, to provisionally cure the protective layer resin; and

second curing the protective layer resin which is provisionally cured, to finally cure the protective layer resin and form the protective laver.

7 . The method of claim 2 , wherein

the protective layer has an outer edge which is furthest from the active region and contacts the protruding part at an area of the protective layer which is adjacent to the outer edge, and

the removing the protective layer from the display panels comprises initial detachment of the protective layer from the display panels, at the area of the protective layer which is adjacent to the outer edge.

8 . The method of claim 1 , further comprising between the providing of the protective layer on the display panels and the removing of the protective layer from the display panels:

removing the display panels together with the protective layer, from the substrate, and

cutting each of display panels which is removed from the substrate.
