Display panel and method of manufacturing the same

Abstract

A method manufacturing a display device includes: forming a pixel circuit in a display area; forming a sacrificial layer on an insulating layer arranged in a non-display area, the sacrificial layer including an isolated pattern hole; forming functional layers and an opposite electrode of an organic light-emitting diode that extends over the display area and the non-display area, the functional layers and the opposite electrode covering the sacrificial layer; irradiating a laser beam to the opposite electrode through the sacrificial layer and the pattern hole from below a substrate; and lifting off the sacrificial layer from the insulating layer and simultaneously, lifting off the opposite electrode to which the laser beam is irradiated, wherein at least a portion of the functional layers is left on a portion of the insulating layer corresponding to the opposite electrode that is removed.

What is claimed is: 
     
         1 . A display panel comprising:
 a substrate comprising:
 an opening area; 
 a display area; and 
 a non-display area, the display area surrounding the opening area, and non-display area being between the opening area and the display area; p 1  an organic light-emitting diode in the display area and including a pixel electrode, an intermediate layer, and an opposite electrode; 
   a dam of a plurality of layers in the non-display area and including an insulating layer; and   a thin-film encapsulation layer extending over the display area and the non-display area,   wherein a pattern layer is in a region between the dam and the opening area, the pattern layer surrounding the opening area, and   the thin-film encapsulation layer covers the pattern layer.   
     
     
         2 . The display panel of  claim 1 , wherein the pattern layer corresponds to at least a portion of functional layers that are patterned on the insulating layer. 
     
     
         3 . The display panel of  claim 2 , wherein the portion of the functional layers that are patterned includes a multi-circle type pattern. 
     
     
         4 . The display panel of  claim 2 , wherein the portion of the functional layers that are patterned includes a plurality of dot patterns. 
     
     
         5 . The display panel of  claim 2 , wherein at least one inorganic encapsulation layer of the thin-film encapsulation layer covers the portion of the functional layers that are patterned and an insulating layer between the functional layers. 
     
     
         6 . The display panel of  claim 1 , wherein the pattern layer corresponds to at least a portion of a patterned conductive layer on the insulating layer. 
     
     
         7 . The display panel of  claim 6 , wherein the patterned conductive layer is on a same layer as the pixel electrode and includes a same material as the pixel electrode.
