Substrate section for flexible display device, method of manufacturing substrate section, organic light emitting display device including substrate, and method of manufacturing organic light emitting display device including substrate

Abstract

A substrate section for a flexible display device is disclosed. The substrate section prevents adhesion loss between a reinforcing layer and a barrier layer, thereby preventing a peel-off phenomenon between an inorganic barrier layer and a reinforcing layer.

What is claimed is: 
     
         1 . A substrate section for a flexible display device, the substrate section comprising:
 a first substrate;   a second substrate disposed above a center region of the first substrate;   a reinforcing layer disposed between the first and second substrates, configured to reinforce adhesion between the first and second substrates;   a first barrier layer configured to contact the reinforcing layer and to cover the second substrate; and   a second barrier layer disposed above the first barrier layer,   wherein the first barrier layer is less dense than the second barrier layer.   
     
     
         2 . The substrate section of  claim 1 , wherein the first substrate is formed of glass. 
     
     
         3 . The substrate section of  claim 1 , wherein the second substrate is formed of a flexible synthetic resin. 
     
     
         4 . The substrate section of  claim 1 , wherein the reinforcing layer is formed of indium tin oxide (ITO). 
     
     
         5 . The substrate section of  claim 1 , wherein each of the first barrier layer and the second barrier layer comprises a plurality of inorganic thin films. 
     
     
         6 . The substrate section of  claim 5 , wherein each of the first barrier layer and the second barrier layer is formed by alternately stacking a silicon oxide (SiO x ) layer and a silicon nitride (SiN x ) layer.
