Display module, display panel, and method for manufacturing the display panel

Abstract

A display module includes a window including a base substrate and a bezel pattern overlapping the base substrate in a plan view, and a display panel. The bezel pattern includes a first bezel pattern extending along an edge of the base substrate, and a second bezel pattern which extends from the first bezel pattern and of which at least a portion defines a transmission area. The display panel includes a glass substrate, an encapsulation substrate on the glass substrate, a sealing member coupling the glass substrate and the encapsulation substrate and overlapping the first bezel pattern in the plan view, a circuit element layer disposed on the glass substrate and including a transistor, and a display element layer disposed on the circuit element layer and including light emitting elements. The display element layer exposes a portion of a layer disposed thereunder, which corresponds to the transmission area.

What is claimed is: 
     
         1 . A mask assembly comprising:
 a frame in which an opening is defined;   a plurality of first sticks coupled to the frame to overlap the opening, wherein the plurality of first sticks extends in a first direction and is arranged in a second direction intersecting the first direction; and   a plurality of second sticks disposed to intersect the plurality of first sticks,   wherein each of the plurality of first sticks comprises a stick portion having a straight line shape and a mask portion coupled to the stick portion and protruding outside the stick portion in the plan view.   
     
     
         2 . The mask assembly of  claim 1 , wherein an edge of the mask portion includes a curved line in the plan view. 
     
     
         3 . The mask assembly of  claim 1 , wherein the mask portion is provided in plural. 
     
     
         4 . The mask assembly of  claim 1 , further comprising a plurality of masks overlapping the plurality of first sticks,
 wherein each of the plurality of masks has a plurality of mask openings.   
     
     
         5 . The mask assembly of  claim 4 , the mask portion overlaps corresponding mask openings of the plurality of mask openings. 
     
     
         6 . The mask assembly of  claim 1 , wherein the frame includes a nickel, a nickel-cobalt alloy, or a nickel-iron alloy. 
     
     
         7 . The mask assembly of  claim 1 , wherein a plurality of coupling recesses into which the plurality of first sticks is coupled are defined in the frame. 
     
     
         8 . The mask assembly of  claim 1 , wherein the mask portion and the stick portion constitute a single unitary body. 
     
     
         9 . The mask assembly of  claim 1 , wherein the plurality of second sticks has a substantially constant width in the first direction. 
     
     
         10 . The mask assembly of  claim 1 , wherein the first sticks include a stainless steel.
