DISPLAY DEVICES AND METHODS OF MANUFACTURING DISPLAY DEVICES

1 . A method of manufacturing a display device, the method comprising:

providing a substrate comprising a display region and a peripheral region;

forming a plurality of display structures at the display region of the substrate;

forming a plurality of blocking structures having heights different from each other at the peripheral region of the substrate; and

alternately forming an organic layer and an inorganic layer on the display structures and the blocking structures.

2 . The method of manufacturing the display device of claim 1 , further comprising:

forming transistors, an insulating interlayer, and wirings on the substrate;

forming an insulation layer on the insulating interlayer to cover the transistors and the wirings; and

forming a protection member at the peripheral region of the substrate to cover the insulation layer and an outermost wiring of the wirings.

3 . The method of manufacturing the display device of claim 2 , wherein the forming of the plurality of blocking structures comprises:

forming a metal layer pattern adjacent to the outermost wiring;

forming a first insulation layer pattern on a portion of the outermost wiring; and

forming a second insulation layer pattern on the metal layer pattern.

4 . The method of manufacturing the display device of claim 3 , wherein the outermost wiring and the metal layer pattern are concurrently formed, and wherein the first and the second insulation layer patterns and the insulation layer are concurrently formed.

5 . The method of manufacturing the display device of claim 3 , wherein the forming of the plurality of display structures comprises:

forming first electrodes on the insulation layer;

forming a pixel defining layer and a spacer on the insulation layer, the pixel defining layer partially exposing the first electrodes;

forming light emitting layers on each of the exposed first electrodes; and

forming a second electrode on the light emitting layers, the pixel defining layer, and the spacer.

6 . The method of manufacturing a display device of claim 5 , wherein forming the plurality of blocking structures further comprises:

forming a third insulation layer pattern on the protection member;

forming a fourth insulation layer pattern on the first insulation layer pattern;

forming a fifth insulation layer pattern on the second insulation layer pattern; and

forming a sixth insulation layer pattern on the fifth insulation layer pattern.

7 . The method of manufacturing a display device of claim 6 , wherein the third insulation layer pattern, the fourth insulation layer pattern, and the fifth insulation layer pattern are concurrently formed with the pixel defining layer.

8 . The method of manufacturing a display device of claim 6 , wherein the sixth insulation layer pattern and the spacer are concurrently formed.
