Abstract

In a flexible display device including flexibility and toughness, and a method of manufacturing the flexible display device, the flexible display device includes a glass substrate, a flexible substrate and a display unit which are sequentially stacked, and the flexible display device has a structure wherein a surface area of the flexible substrate is larger than a surface area of the glass substrate. A volume of the device may be significantly reduced for convenience of portability since a flexible area where the glass substrate is not located may be folded or rolled. Also, a stable circuit connection may be guaranteed since the driving chip is installed on a hard area which does not go through a heating process in order to separate the glass substrate and the flexible substrate during the manufacturing process.

Claims (15)

1. A flexible display device, comprising:

a glass substrate;

a flexible substrate including a first portion and a second portion; and

a display unit including a first display portion disposed on the first portion of the flexible substrate and a second display portion permanently attached to the glass substrate via the second portion of the flexible substrate,

a surface area of the flexible substrate being greater than a surface area of the glass substrate.

2. The flexible display device of claim 1 , wherein the first display portion of the display unit, which is not permanently attached to the glass substrate, deforms together with the first portion of the flexible substrate within a range allowed by flexibility of the flexible substrate.

3. The flexible display device of claim 2 , wherein a driving chip is installed on a side of the flexible substrate where the glass substrate is located.

4. The flexible display device of claim 3 , further comprising a silicone stiffener for attaching the glass substrate and the flexible substrate disposed around a border line between the first and second portions of the flexible substrate.

5. The flexible display device of claim 4 , wherein a corner of a cutting plane of the glass substrate on a side of the border line is chamfered.

6. The flexible display device of claim 3 , wherein a corner of a cutting plane of the glass substrate on a side of the border line is chamfered.

7. The flexible display device of claim 2 , wherein a corner of a cutting plane of the glass substrate on a side of the border line is chamfered.

8. The flexible display device of claim 2 , further comprising a silicone stiffener for attaching the glass substrate and the flexible substrate disposed around a border line between the first and second portions of the flexible substrate.

9. The flexible display device of claim 1 , wherein a corner of a cutting plane of the glass substrate on a side of the border line is chamfered.

10. The flexible display device of claim 1 , further comprising a silicone stiffener for attaching the glass substrate and the flexible substrate disposed around a border line between the first and second portions of the flexible substrate.

11. The flexible display device of claim 1 , wherein a driving chip is installed on a side of the flexible substrate where the glass substrate is located.
