Display devices and methods of manufacturing display devices

Abstract

A display device includes a substrate including a display region and a peripheral region, display structures at the display region of the substrate, a plurality of blocking structures at the peripheral region of the substrate wherein the blocking structures have heights different from each other, an organic layer on the display structures and the blocking structures, and an inorganic layer on the organic layer.

What is claimed is: 
     
         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.
