Abstract

Provided is a display device including: a bottom member; a display panel on the bottom member, the display panel configured to emit light; a top member on the display panel; a touch screen panel on the top member; and a groove region formed by removing at least a portion of at least one of the top member and the bottom member at a bent portion of the display device.

Claims (22)

1. A method of manufacturing a display device, the method comprising:

forming a display panel configured to emit light;

forming a top member and a bottom member on upper and lower surfaces of the display panel, respectively;

forming a first groove region by removing at least a portion of at least one of the top member and the bottom member at a bent portion of the display device;

forming a touch screen panel on the display panel; and

bending the display device at the first groove region,

wherein the forming of the touch screen panel on the display panel comprises:

forming first and second adhesives on upper and lower surfaces of the touch screen panel, respectively;

forming a transparent member on the second adhesive;

forming a second groove region by removing at least a portion of at least one of the first adhesive, the second adhesive, and the transparent member at the bent portion of the display device; and

forming the touch screen panel at where the first adhesive, the second adhesive, and the transparent member are formed, on the display panel at where the bottom member and the top member are formed.

2. The method of claim 1 , wherein the first groove region comprises:

a first groove formed by removing at least a portion of the top member at the bent portion of the display device; and

a second groove formed by removing at least a portion of the bottom member at the bent portion of the display device.

3. The method of claim 1 , wherein a first neutral plane at the bent portion of the display device is formed within the display panel.

4. The method of claim 1 , wherein the second groove region comprises:

a third groove formed by removing at least a portion of the transparent member and the second adhesive at the bent portion of the display device; and

a fourth groove formed by removing at least a portion of the first adhesive at the bent portion of the display device.

5. The method of claim 1 , wherein a second neutral plane at the bent portion of the display device is formed within the touch screen panel.

6. The method of claim 1 , wherein the touch screen panel has mobility between the first and second adhesives.

7. The method of claim 1 , wherein the forming of the second groove region comprises irradiating a laser at the first adhesive, the second adhesive, and the transparent member to remove the first adhesive, the second adhesive, and the transparent member at the bent portion of the display device.

8. The method of claim 1 , wherein the forming of the first groove region comprises irradiating a laser at the top member and the bottom member to remove the top member and the bottom member at the bent portion of the display device.
