Abstract

A method of manufacturing a display panel includes forming a pixel-defining layer on a substrate, disposing a mask on the pixel-defining layer on a first region of the substrate, and forming a first emission layer, and disposing the mask on the pixel-defining layer on a second region of the substrate, and forming a second emission layer.

Claims

exact text as granted — not AI-modified
1 .- 17 . (canceled) 
     
     
         18 . A display panel, comprising:
 a substrate having at least five alignmarks thereon;   a display unit including a pixel-defining layer that is on the substrate, and an emission layer that is on the pixel-defining layer; and   an encapsulation unit that is on the display unit.   
     
     
         19 . The display panel of  claim 18 , wherein four alignmarks of the at least five alignmarks are on corners of the substrate, respectively, and at least one alignmark of the at least five alignmarks is on a center region of the substrate. 
     
     
         20 . The display panel of  claim 18 , wherein the emission layer includes:
 a first emission layer on a portion of the pixel-defining layer; and   a second emission layer on residual portions of the pixel-defining layer.   
     
     
         21 . The display panel of  claim 20 , wherein the first emission layer and the second emission layer are formed by using a same mask. 
     
     
         22 . The display panel of  claim 20 , wherein the first emission layer and the second emission layer are formed while crossing each other on at least one portion of the pixel-defining layer.
