Abstract

A flexible display device including a display area for displaying an image and a non-display area neighboring the display area includes: a flexible substrate including a plurality of chamfers on respective ends corresponding to the non-display area; a display provided on the flexible substrate corresponding to the display area and displaying the image; and a driver provided on the flexible substrate corresponding to the non-display area and connected to the display.

First claim

What is claimed is:

1. A flexible display device including a display area for displaying an image and a non-display area neighboring the display area, the flexible display device comprising:
a flexible substrate including a plurality of chamfers on respective ends corresponding to the non-display area;
a display on the flexible substrate corresponding to the display area and displaying the image; and
a driver on the flexible substrate corresponding to the non-display area and connected to the display, wherein:
the flexible substrate includes a flexible substrate main body and an insulation layer provided on the flexible substrate main body,
at least the insulation layer from among the flexible substrate main body and the insulation layer forms each chamfer,
each chamfer is in the insulation layer, and
each chamfer exposes the flexible substrate main body.

2. The flexible display device as claimed in claim 1 , wherein the driver is provided between neighboring chamfers.

3. The flexible display device as claimed in claim 1 , wherein:
the flexible substrate main body includes an organic material, and
the insulation layer includes an inorganic material.

4. The flexible display device as claimed in claim 1 , wherein each chamfer is an edge of the flexible substrate main body and the insulation layer.

5. The flexible display device as claimed in claim 1 , wherein each chamfer is a groove.

6. The flexible display device as claimed in claim 1 , further including an encapsulator corresponding to the display area, the encapsulator sealing the display together with the flexible substrate.

7. The flexible display device as claimed in claim 1 , wherein the display includes an organic light emitting diode.

8. The flexible display device as claimed in claim 1 , further including a window on the display, the window covering the display area and the non-display area.

9. The flexible display device as claimed in claim 8 , wherein an edge of the window neighboring each chamfer of the flexible substrate is curved.

10. A flexible display device including a display area for displaying an image and a non-display area neighboring the display area, the flexible display device comprising:
a flexible substrate including a first bevel on a first end of the flexible substrate corresponding to the non-display area and a second bevel on a second end of the flexible substrate corresponding to the non-display area;
a display on the flexible substrate corresponding to the display area and displaying the image; and
a driver on the flexible substrate corresponding to the non-display area and connected to the display, wherein:
the flexible substrate includes a flexible substrate main body and an insulation layer provided on the flexible substrate main body, and
the first and second bevels isolate a part the insulation layer on an outer portion of the flexible substrate main body from a part of insulation layer on a portion of the flexible substrate main body having the driver thereon.

11. The flexible display device as claimed in claim 10 , wherein
the first and second bevels are in the insulation layer, and
the first and second bevels expose the flexible substrate main body.

12. The flexible display device as claimed in claim 10 , wherein:
the first and second bevels are edges of the flexible substrate main body and the insulation layer.

13. The flexible display device as claimed in claim 10 , wherein the display includes an organic light emitting diode.

14. The flexible display device as claimed in claim 10 , further including a window on the display, the window covering the display area and the non-display area.

15. The flexible display device as claimed in claim 14 , wherein an edge of the window neighboring the first and second bevels of the flexible substrate is curved.

16. A flexible display device including a display area for displaying an image and a non-display area neighboring the display area, the flexible display device comprising:
a flexible substrate including a first bevel on a first end of the flexible substrate corresponding to the non-display area and a second bevel on a second end of the flexible substrate corresponding to the non-display area;
a display on the flexible substrate corresponding to the display area and displaying the image; and
a driver on the flexible substrate corresponding to the non-display area and connected to the display, wherein:
the flexible substrate includes a flexible substrate main body and an insulation layer provided on the flexible substrate main body,
at least the insulation layer from among the flexible substrate main body and the insulation layer forms the first bevel and the second bevel,
the first bevel and the second bevel are in the insulation layer, and
the first bevel and the second bevel expose the flexible substrate main body.
