Abstract

Discussed is a display device and a method of manufacturing the display device. The display device according to one example includes a display panel including a first substrate and a second substrate facing and coupled to the first substrate, wherein the first substrate includes a display part in which a plurality of pixels are formed, a bending part formed at one side of the display part, and a pad part formed at an end of the bending part; a back film adhered to a portion, corresponding to the display part and the pad part, in a bottom of the first substrate; and a supporting member formed to guide the bending part and support the back film adhered to a portion corresponding to the display part.

First claim

What is claimed is:

1. A display device comprising:
a display panel comprising a first substrate and a second substrate facing-coupled to the first substrate, wherein the first substrate comprises a display part in which a plurality of pixels are formed, a bending part formed at one side of the display part, and a pad part formed at an end of the bending part;
a back film adhered to a portion, corresponding to the display part and the pad part, in a bottom of the first substrate; and
a supporting member formed to guide the bending part and support the back film adhered to a portion corresponding to the display part,
wherein:
the supporting member includes a side surface facing the bending part, a bottom surface facing the back film adhered to a portion corresponding to the pad part of the first substrate, and a top surface facing the first substrate,
the side surface of the supporting member facing the bending part is formed to be rounded,
the back film provided to the portion corresponding to the display part is adhered between the bottom of the first substrate and the top surface of the supporting member, and
the back film provided to the portion corresponding to the pad part is adhered to the bottom surface of the supporting member.

2. The display device of claim 1 , wherein in the back film, a separation space is formed between the portion corresponding to the display part and the portion corresponding to the pad part.

3. The display device of claim 2 , wherein the separation space corresponds to the bending part.

4. The display device of claim 1 , wherein the back film comprises:
a first film adhered to the portion corresponding to the display part; and
a second film adhered to the portion corresponding to the pad part, the first film and the second film being separated from each other in an area corresponding to the bending part.

5. The display device of claim 1 , wherein the first substrate is a flexible thin film substrate.

6. The display device of claim 5 , wherein the first substrate includes a plastic material or a metal foil.

7. The display device of claim 1 , further comprising an optical film disposed on the second substrate and configured to polarize light.

8. The display device of claim 1 , wherein the pad part is electrically connected to a flexible circuit board that comprises a panel driver.

9. The display device of claim 1 , wherein the pad part is electrically connected to a driving integrated circuit that comprises a panel driver.

10. A flexible display device comprising:
a first substrate including a display part, a pad part, and a bending part disposed between the display and pad parts, the display part including a plurality of pixels;
a second substrate disposed on the display part of the first substrate;
a first back film adhered to the display part and a second back film adhered to the pad part of the first substrate; and
a supporting member including a top surface adhered to the first back film, a rounded side surface in contact with the bending part of the first substrate, and a bottom surface directly in contact with the second back film.

11. The flexible display device of claim 10 , wherein a separation space is formed between the first back film and the second back film.

12. The flexible display device of claim 11 , wherein the separation space corresponds to the bending part.

13. The flexible display device of claim 10 , wherein the first substrate is a flexible thin film substrate.

14. The flexible display device of claim 13 , wherein the first substrate includes a plastic material or a metal foil.
