## 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.

## Claims

### Claim 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.

### Claim 2 (depends on 1)

The display device of claim 1, wherein the metal protrusion portion is spaced from the ground pattern.

### Claim 3 (depends on 1)

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.

### Claim 4 (depends on 1)
