Abstract

A display device includes a front display area, a first side display area, a second side display area, a corner display area, a display panel, and a light guide member. The first side display area extends from a first side of the front display area. The second side display area extends from a second side of the front display area. The corner display area is disposed between the first side display area and the second side display area. The display panel overlaps the front display area and does not overlap the corner display area. The light guide member is disposed in the corner display area.

Claims (61)

1. A display device, comprising:

a front display area;

a first side display area extending from a first side of the front display area;

a second side display area extending from a second side of the front display area;

a corner display area disposed between the first side display area and the second side display area;

a display panel overlapping the front display area and not overlapping the corner display area; and

a light guide member disposed in the corner display area.

2. The display device of claim 1 , wherein the light guide member is configured to guide light emitted from the display panel and transmit the light to the corner display area.

3. The display device of claim 2 , wherein the light guide member at least partially overlaps the display panel.

4. The display device of claim 3 , wherein:

the display panel comprise a first pixel area and a second pixel area;

the second pixel area comprises a first pixel and a second pixel;

the corner display area comprises a first light emitting area and a second light emitting area; and

the light guide member is configured to:

guide light emitted from the first pixel and transmit the light from the first pixel to the first light emitting area; and

guide light emitted from the second pixel and transmit the light from the second pixel to the second light emitting area.

5. The display device of claim 4 , wherein, in a thickness direction, the light guide member overlaps the second pixel area in the front display area.

6. The display device of claim 5 , wherein:

the display panel comprises a substrate, a light emitting layer disposed on the substrate, and an encapsulation layer disposed on the light emitting layer; and

the light guide member directly contacts the encapsulation layer.

7. The display device of claim 5 , wherein:

the display panel comprises a first side area, a second side area spaced apart from the first side area, and a corner area defined in a space between the first side area and the second side area; and

the corner area overlaps the corner display area.

8. The display device of claim 5 , further comprising:

a semi-transmissive film disposed on the light guide member and overlapping the display panel.

9. The display device of claim 8 , further comprising:

a light emission pattern disposed in the corner display area and overlapping the light guide member in a thickness direction.

10. The display device of claim 9 , wherein the semi-transmissive film does not overlap the light emission pattern in the thickness direction.

11. The display device of claim 10 , wherein a curvature of the light guide member is substantially equal to a curvature of the light emission pattern.

12. A display device, comprising:

a first display area;

a second display area adjacent to the first display area;

a display panel disposed in the second display area and not overlapping the first display area;

a semi-transmissive film disposed on the light guide member and overlapping the second pixel area; and

a light guide member disposed in the first display area,

wherein:

the display panel comprises a first pixel area and a second pixel area,

the light guide member overlaps the second pixel area, and

the light guide member and the semi-transmissive film do not overlap the first pixel area in a thickness direction.

13. The display device of claim 12 , wherein the light guide member is configured to guide light emitted from the second pixel area and transmit the light to the first display area.

14. The display device of claim 12 , further comprising:

a diffraction pattern layer disposed on the light guide member in the first display area.

15. The display device of claim 14 , wherein:

the diffraction pattern layer is configured to diffract light emitted from the display panel to generate a replicated light emitting area; and

the display device is configured to display the replicated light emitting area on the first display area.

16. A display device comprising:

a first display area;

a second display area adjacent to the first display area;

a display panel disposed in the second display area and not overlapping the first display area;

a light guide member disposed in the first display area; and

a diffraction pattern layer disposed on the light guide member in the first display area,

wherein the diffraction pattern layer comprises:

a plurality of diffraction patterns; and

a protective layer disposed on the plurality of diffraction patterns.

17. A display device comprising:

a first display area;

a second display area adjacent to the first display area;

a display panel disposed in the second display area and not overlapping the first display area;

a light guide member disposed in the first display area;

a diffraction pattern layer disposed on the light guide member in the first display area; and

a light emission pattern disposed between the light guide member and the diffraction pattern layer.
