Organic light emitting diode display

Abstract

An organic light emitting diode display includes a display substrate including an organic light emitting element and a driving circuit part, an encapsulation substrate sealing the display substrate, and a sealing portion between the display substrate and the encapsulation substrate, the sealing portion including a plurality of sealing frame portions around the display substrate, and a first sealing frame portion of the plurality of sealing frame portions being adjacent to a pad portion, wherein at least one of a width of an edge of the sealing portion and a width of the first sealing frame portion is wider than a width of a sealing frame portion other than the first sealing frame portion.

What is claimed is: 
     
         1 . An organic light emitting diode display, comprising:
 a display substrate including an organic light emitting element and a driving circuit part;   an encapsulation substrate sealing the display substrate; and   a sealing portion between the display substrate and the encapsulation substrate, the sealing portion including a plurality of sealing frame portions around the display substrate, and a first sealing frame portion of the plurality of sealing frame portions being adjacent to a pad portion,   wherein at least one of a width of an edge of the sealing portion and a width of the first sealing frame portion is wider than a width of a sealing frame portion other than the first sealing frame portion.   
     
     
         2 . The organic light emitting diode display as claimed in  claim 1 , further comprising a sealing material at least at one inner edge of the sealing portion, the sealing material having a triangular shape. 
     
     
         3 . The organic light emitting diode display as claimed in  claim 2 , wherein the sealing material is reinforced at two or more edges among inner edges of the sealing portion. 
     
     
         4 . The organic light emitting diode display as claimed in  claim 2 , wherein the sealing material has a right-triangular shape, the sealing material fitting into an inner right-triangular shape of the inner edge of the sealing portion. 
     
     
         5 . The organic light emitting diode display as claimed in  claim 2 , wherein the sealing material is only at edges of the sealing portion among all portions of the sealing portion, the sealing material being in direct contact with the inner edges of the sealing portion. 
     
     
         6 . The organic light emitting diode display as claimed in  claim 1 , wherein the width of the first sealing frame portion is wider than the width of sealing frame portions other than the first sealing frame portion by about 10% or more. 
     
     
         7 . The organic light emitting diode display as claimed in  claim 1 , further comprising a protruding portion on and protruding away from at least one of the sealing frame portions, a width of the protruding portion being wider than the sealing frame portions. 
     
     
         8 . The organic light emitting diode display as claimed in  claim 7 , wherein the protruding portion has a semicircular shape. 
     
     
         9 . The organic light emitting diode display as claimed in  claim 8 , wherein the protruding portion is at an opposite side. 
     
     
         10 . The organic light emitting diode display as claimed in  claim 1 , wherein the width of the edge of the sealing portion is measured along a direction that is oblique with respect to a direction of the width of any adjacent sealing frame portion.
