Organic light emitting display device with a bezel and rib and a secure interconnection there between

1. An organic light emitting display device comprising:

an organic light emitting display panel;

a bezel comprising a lower surface and a plurality of side walls extending from edges of the lower surface, the lower surface and the side walls forming a receiving space in which the display panel is received;

a first rib formed on at least one side wall, the rib having two opposed sides;

a protective window disposed on the top of the bezel; and

a groove formed on the protective window, wherein the groove comprised an opening that is enclosed on two opposed sides;

wherein the first rib is coupled with the groove so that the groove engages the ribs such that both of the opposed sides are positioned proximate the opposed sides of the groove.

2. The organic light emitting display device as claimed in claim 1 , wherein the first rib comprises a fold-over portion.

3. The organic light emitting display device as claimed in claim 2 , wherein the fold-over of the first rib is formed by bending a portion of a side wall.

4. The organic light emitting display device as claimed in claim 3 , wherein the fold-over forms an auxiliary side wall.

5. The organic light emitting display device as claimed in claim 4 , wherein substantially no space exists between the sidewall and the auxiliary side wall.

6. The organic light emitting display device as claimed in claim 4 , wherein the auxiliary sidewall extends to about the lower surface of the bezel.

7. The organic light emitting display device as claimed in claim 2 , wherein the fold-over is folded outwardly relative to the receiving space.

8. The organic light emitting display device as claimed in claim 2 , wherein the fold-over is folded inwardly relative to the receiving space.

9. The organic light emitting display device as claimed in claim 2 , wherein the fold-over comprises a rounded profile.

10. The organic light emitting display device as claimed in claim 1 , wherein the bezel further comprises at least one a second rib disposed between the side wall and the first rib of the bezel and substantially orthogonal thereto.

11. The organic light emitting display device as claimed in claim 10 , wherein the second rib is adhered to a projecting part extending from the protective window.

12. The organic light emitting display device as claimed in claim 1 , wherein the groove is formed on an inner side of the protective window in a position corresponding to the first rib.

13. The organic light emitting display device as claimed in claim 1 , wherein the bezel comprises three side walls, corresponding to three sides of the display panel.

14. The organic light emitting display device as claimed in claim 13 , wherein each sidewall comprises a first rib.

15. The organic light emitting display device as claimed in claim 1 , wherein an adhesive member is disposed between the bezel and the protective window.

16. The organic light emitting display device as claimed in claim 15 , wherein at least a portion of the adhesive member is disposed in a contact surface between the first rib and the groove.

17. The organic light emitting display device as claimed in claim 15 , wherein the adhesive member comprises at least one of an adhesive and a vinyl tape.

18. The organic light emitting display device as claimed in claim 1 , wherein a polarizing plate is disposed between the display panel and the protective window.

19. The organic light emitting display device as claimed in claim 1 , wherein the bezel comprises at least one of stainless steel (STS), magnesium, magnesium alloy, and aluminum.
