Display apparatus having an outwardly curved dam structure and method of manufacturing the same

1. A display device comprising:

a display panel to display an image on a display surface of the display panel;

a transparent protective member arranged on the display surface;

a dam unit interposed between the display panel and the transparent protective member and formed to correspond to edges of the display panel; and

a transparent filling layer that fills a space formed by the display panel, the transparent protective member, and the dam unit,

wherein walls of the dam unit are outwardly bent in a direction extending from an inside surface of the display panel to an outside surface of the display panel, and

wherein display panel has a shape of a polygon, and the walls of the dam unit are formed such that, a distance between edges of the walls of the dam unit and edges of the polygon increase from centers of the edges of the polygon to the vertexes of the polygon.

2. The display device of claim 1 , wherein outer walls of the dam unit are formed parallel with inner walls of the dam unit.

3. The display device of claim 1 , wherein outer walls of the dam unit are formed adjacent to the edges of the display panel.

4. The display device of claim 1 , wherein the dam unit is formed by ink-printing a pattern of the dam unit on the transparent protective member.

5. The display device of claim 1 , wherein the dam unit is formed by taping a pattern of the dam unit on the transparent protective member.

6. The display device of claim 1 , wherein the dam unit is formed by applying a hardening resin on the transparent protective member and hardening the hardening resin.

7. The display device of claim 1 , wherein the transparent protective member is a glass substrate, and the transparent filling layer is formed by hardening a liquid-type transparent filling.

8. The display device of claim 1 , wherein the transparent filling is an acrylic material or resin.

9. The display device of claim 1 , wherein inner walls of the dam unit are concave.

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

forming a dam unit on a transparent protective member, arranged on a display panel, adjacent to edges of the display panel, the dam unit having a plurality of sides, each side having a curvature;

depositing a liquid-type transparent filling on the transparent protective member, such that the dam unit and the liquid-type transparent filling are interposed between the transparent protective member and the display panel;

pressing the transparent protective member and the display panel toward each other; and

hardening the liquid-type transparent filling,

wherein the display panel has a polygon shape, and the sides of the dam unit are formed such that, a distance between edges of the sides of the dam unit and edges of the polygon increase from centers of the edges of the polygon to vertexes of the polygon.

11. The method of claim 10 , wherein outer walls of the dam unit are formed parallel with inner walls of the dam unit.

12. The method of claim 10 , wherein outer walls of the dam unit are formed along the edges of the display panel.

13. The method of claim 10 , wherein the dam unit is formed by ink-printing a pattern of the dam unit on the transparent protective member.

14. The method of claim 10 , wherein the dam unit is formed by taping a pattern of the dam unit on the transparent protective member.

15. The method of claim 10 , wherein the forming of the dam unit comprises:

applying a hardening resin on the transparent protective member; and

hardening the hardening resin.

16. The method of claim 10 , wherein the transparent protective member is a glass substrate.

17. The method of claim 10 , wherein the transparent filling is an acrylic material or resin.

18. The method of claim 10 , wherein inner walls of the dam unit are concave.
