Display device

Abstract

A display device includes a display module including a display panel, a circuit board electrically connected to the display panel, and a driving device mounted on the circuit board and configured to apply an electrical signal to the display panel, and a case including a metal body portion, and a metal protrusion portion protruding from the metal body portion and coupled to the display module, wherein the circuit board includes a ground layer, an insulating layer, and a ground pattern electrically connected to the ground layer and facing the metal protrusion portion.

What is claimed is: 
     
         1 . A display device comprising:
 a display module comprising:
 a display panel; 
 a circuit board electrically connected to the display panel; and 
 a driving device mounted on the circuit board and configured to apply an electrical signal to the display panel; and 
   a case comprising:
 a metal body portion; and 
 a metal protrusion portion protruding from the metal body portion and coupled to the display module, 
   wherein the circuit board comprises:
 a ground layer; 
 an insulating layer; and 
 a ground pattern electrically connected to the ground layer and facing the metal protrusion portion, and 
   wherein the metal body portion comprises:
 a bottom portion; and 
 a sidewall portion extending from the bottom portion toward the display module, and having the metal protrusion portion thereon. 
   
     
     
         2 . The display device of  claim 1 , wherein the metal protrusion portion is spaced from the ground pattern. 
     
     
         3 . The display device of  claim 1 , wherein the display panel further comprises a first pad part electrically connected to the circuit board, and
 wherein the circuit board further comprises a second pad part connected to the first pad part by a conductive adhesive member.   
     
     
         4 . The display device of  claim 1 , wherein the circuit board comprises a flexible circuit board.
