Abstract

A display device including a display panel which displays an image, a driving circuit substrate disposed on a rear surface of the display panel and configured to control the display panel to display the image; a protective cover coupled to the display panel while interposing the driving circuit substrate there between to protect the driving circuit substrate; and an antenna pattern attached to the protective cover and configured to transmit and receive a wireless signal.

Claims

1. A display device comprising:

a display panel configured to display an image;

a driving circuit substrate disposed on a rear surface of the display panel and configured to control the display panel to display the image;

a protective cover coupled to the display panel while interposing the driving circuit substrate there between to protect the driving circuit substrate; and

an antenna pattern part attached to the protective cover and configured to transmit and receive a wireless signal,

wherein;

the antenna pattern part comprises a first antenna pattern and a second antenna pattern;

the protective cover comprises a rear portion covering a rear surface of the driving circuit substrate; and

the first antenna pattern and the second antenna pattern are disposed at end portions in a longitudinal direction of the rear portion.

2. The display device of claim 1, wherein the protective cover further comprises

a side portion angled from the rear portion to contact a side surface of the display panel.

3. The display device of claim 2, wherein the antenna pattern part is disposed on the rear portion of the protective cover.

4. The display device of claim 1, wherein the antenna pattern part comprises a metal thin film layer.
