Abstract

An embodiments may be related to a display device. A display device may include display layer and an antenna. The display layer may comprise a first display area including an exposed area and a cover area, a folding display area adjacent to the first display area, and a second display area adjacent to the folding area. The antenna disposed on the exposed area of the first display area, wherein the second display area covers the cover area of the first display area and exposes the exposed area of the first display area, when the folding display area is folded.

Claims (34)

1. A display device comprising:

a display layer comprising a first display area including an exposed area and a cover area, a folding display area adjacent to the first display area, and a second display area adjacent to the folding display area;

a sensor layer disposed on the display layer;

an antenna provided in the sensor layer and overlapping the exposed area of the first display area on a plane;

an optical film disposed between the display layer and the antenna; and

a compensation film disposed between the optical film and the antenna,

when the folding display area is folded, the second display area covers the cover area of the first display area and exposes the exposed area of the first display area, and

wherein the antenna is disposed on the display layer.

2. The display device of claim 1 ,

wherein the sensor layer comprises:

a first conductive layer disposed on the display layer;

an insulating layer disposed on the first conductive layer; and

a second conductive layer disposed on the insulating layer.

3. The display device of claim 2 ,

wherein the second conductive layer of the sensor layer comprises an auxiliary pattern configured to sense an external input.

4. The display device of claim 1 , wherein the display layer comprises:

a first electrode;

a light emitting layer disposed on the first electrode; and

a second electrode disposed on the light emitting layer.

5. The display device of claim 1 , wherein the exposed area comprises:

a first auxiliary display area, a second auxiliary display area, and a non-display area positioned between the first and second auxiliary display areas.

6. The display device of claim 1 , further comprising: an auxiliary display layer overlapping the second display area,

wherein an image displaying direction of the second display area is opposite to an image displaying direction of the auxiliary display layer.

7. The display device of claim 1 , wherein the display layer comprises a main display area, a first auxiliary display area protruded from the main display area, and a second auxiliary display area protruded from the main display area,

wherein a width in a first direction of the main display area is greater than a width in the first direction of the first and second auxiliary display areas, and the exposed area comprises a portion of the main display area and the first and second auxiliary display areas.

8. The display device of claim 7 , wherein each of the first and second auxiliary display area comprises a first area and a second area, and wherein an image display resolution of the second area is higher than an image display resolution of the first area.

9. A display device comprising:

a display layer comprising a first display area including an exposed area and a cover area, a folding display area adjacent to the first display area, and a second display area adjacent to the folding display area;

a sensor layer disposed on the display layer;

an antenna provided in the sensor layer and overlapping the exposed area of the first display area on a plane;

a compensation film disposed between the display layer and the antenna; and

an optical film disposed on the compensation film,

when the folding display area is folded, the second display area covers the cover area of the first display area and exposes the exposed area of the first display area, and

wherein the antenna is disposed between the compensation film and the optical film.
