Display device having touch sensing part

Abstract

A display device includes: a first substrate including a first region, a third region spaced apart from and surrounding the first region, and a second region located between the first region and the third region; a second substrate opposite to the first substrate; a display element including a first electrode on the first substrate, a light emitting layer provided on the first electrode, and a second electrode provided on the light emitting layer; a touch sensing part disposed on the second substrate; and a sealing member provided on the third region of the first substrate, the sealing member joining the first substrate and the second substrate, wherein the second electrode overlaps with the touch sensing part when viewed on a plane, and an end of the second electrode is spaced apart from an end of the touch sensing part at a certain distance in the direction of the sealing member in the second region.

         3 . The display device of  claim 2 , wherein the end of the touch sensing part is disposed closer to the sealing member than the end of the second electrode when viewed perpendicularly to the major surface of the first substrate. 
     
     
         4 . The display device of  claim 2 , wherein the end of the second electrode is disposed closer to the sealing member than the end of the touch sensing part when viewed perpendicularly to the major surface of the first substrate. 
     
     
         5 . The display device of  claim 4 , wherein the second electrode is disposed on the display region and the first region, and does not overlap the sealing member. 
     
     
         6 . The display device of  claim 4 , wherein the second electrode is disposed on the display region and the first region, and partially overlaps the sealing member. 
     
     
         7 . The display device of  claim 6 , wherein the end of the second electrode extends to a lower surface of the sealing member. 
     
     
         8 . A display device, comprising:
 a first substrate including a display region including at least one light emitting element and a non-display region adjacent to at least one side of the display region, the at least one light emitting element including a first electrode disposed on the first substrate, a light emitting layer disposed on the first electrode, and a second electrode disposed on the light emitting layer;   a second substrate opposite to the first substrate;   a sealing member disposed between the non-display region of the first substrate and the second substrate, the sealing member joining the first substrate and the second substrate; and   a touch sensing part disposed on the second substrate,   wherein the sealing member and the second electrode do not overlap each other, and the sealing member and the touch sensing part do not overlap each other.   
     
     
         9 . The display device of  claim 8 , wherein:
 the non-display region of the first substrate includes a first region adjacent to the display region and a second region adjacent to the first region, and   the sealing member is located in the second region of the non-display region of the first substrate.   
     
     
         10 . The display device of  claim 9 , wherein an end of the touch sensing part and an end of the second electrode are located in the first region of the non-display region of the first substrate. 
     
     
         11 . The display device of  claim 10 , wherein the end of the touch sensing part is disposed closer to the sealing member than the end of the second electrode when viewed perpendicularly to a major surface of the first substrate. 
     
     
         12 . The display device of  claim 10 , wherein the end of the second electrode is disposed closer to the sealing member than the end of the touch sensing part when viewed perpendicularly to a major surface of the first substrate. 
     
     
         13 . The display device of  claim 12 , wherein the second electrode is disposed on the display region and the first region, and does not overlap the sealing member. 
     
     
         14 . The display device of  claim 13 , wherein the first region includes a non-overlapping portion at which the second electrode and the touch sensing part do not overlap each other. 
     
     
         15 . The display device of  claim 10 , wherein the end of the second electrode is spaced apart from the end of the touch sensing part in a direction of the sealing member in the first region.
