Display panel

Abstract

A display panel is provided. The display panel includes a first substrate and a second substrate. The first substrate has a display area and the second substrate is arranged opposite to the first substrate. The display panel further includes a display layer. The display layer is positioned between the first substrate and the second substrate. The display panel also includes a sealant. The sealant is positioned between the first substrate and the second substrate and outside the display area. The sealant has an outline, and at least one portion of the outline is wavy.

What is claimed is: 
     
         1 . A display panel, comprising:
 a first substrate having a display area;   a second substrate arranged opposite to the first substrate;   a display layer positioned between the first substrate and the second substrate; and   a sealant positioned between the first substrate and the second substrate and outside the display area, wherein the sealant has an outline and at least one portion of the outline is wavy.   
     
     
         2 . The display panel as claimed in  claim 1 , wherein the first substrate comprises a first lateral edge, and a width of a part of the sealant in a direction perpendicular to the first lateral edge of the first substrate changes in the narrow-wide-narrow manner. 
     
     
         3 . The display panel as claimed in  claim 2 , wherein the first substrate further comprises a second lateral edge connected to the first lateral edge via an intersection point, wherein the part of the sealant is positioned adjacent to the intersection point. 
     
     
         4 . The display panel as claimed in  claim 3 , wherein the first substrate further comprises a third lateral edge, wherein the first lateral edge, the second lateral edge and the third lateral edge are straight, and a first included angle formed between the first lateral edge and the second lateral edge is less than a second included angle formed between the second lateral edge and the third lateral edge. 
     
     
         5 . The display panel as claimed in  claim 1 , wherein the sealant extends along a path, and a width of a part of the sealant in a direction perpendicular to the path changes in a narrow-wide-narrow manner. 
     
     
         6 . The display panel as claimed in  claim 5 , wherein the path comprises a first straight path, a curved path, and a second straight path, the curved path is between the first straight path and the second straight path, and the part of the sealant extends along the curved path. 
     
     
         7 . The display panel as claimed in  claim 1 , wherein the sealant comprises a first straight segment, a curved segment and a second straight segment, and the curved segment is between the first straight segment and the second straight segment. 
     
     
         8 . The display panel as claimed in  claim 7 , wherein the at least one portion of the outline is positioned corresponding to the curved segment. 
     
     
         9 . The display panel as claimed in  claim 1 , wherein the at least one portion of the outline is positioned adjacent to a lateral edge of the first substrate. 
     
     
         10 . The display panel as claimed in  claim 1 , wherein the at least one portion of the outline is positioned adjacent to the display layer. 
     
     
         11 . The display panel as claimed in  claim 1 , wherein the sealant comprises:
 a first curved segment; and a second curved segment;   wherein the first curved segment has a first rotation radius (r 1 ) and the second curved segment has a second rotation radius (r 2 );   wherein the first rotation radius (r 1 ) is greater than the second rotation radius (r 2 ).   
     
     
         12 . The display panel as claimed in  claim 11 , wherein the first rotation radius (r 1 ) and the second rotation radius (r 2 ) satisfy the equation: 0<r 2 /r 1 <1.
