Abstract

An organic light emitting diode display device includes a substrate body that is divided into a display area and a neighboring area; an organic light emitting diode formed in the display area of the substrate body; a barrier film that is attached to the substrate body and covers the organic light emitting diode; and an adhesive agent disposed between the neighboring area of the substrate body and the barrier film. In addition, a groove pattern is recessed on one surface of the barrier film that is in contact with the adhesive agent.

Claims (48)

1. An organic light emitting diode display device, comprising:

a substrate body that is divided into a display area and a neighboring area;

an organic light emitting diode formed in the display area of the substrate body;

a barrier film that is attached to the substrate body with the organic light emitting diode disposed between the barrier film and the substrate body, the barrier film comprising an inorganic barrier layer and an organic barrier layer formed on the inorganic barrier layer, the organic barrier layer disposed spaced apart from the substrate body by the inorganic barrier layer; and

an adhesive agent disposed between the neighboring area of the substrate body and the barrier film,

with a groove pattern being recessed on the surface of the barrier film that is in contact with the adhesive agent.

2. The organic light emitting diode display device of claim 1 , wherein

the inorganic barrier layer is formed on the adhesive agent.

3. The organic light emitting diode display device of claim 2 , wherein

the barrier film further includes one or more additional inorganic barrier layers formed on the organic barrier layer.

4. The organic light emitting diode display device of claim 3 , wherein

the barrier film further includes one or more additional organic barrier layer formed on the additional inorganic barrier layers.

5. The organic light emitting diode display device of claim 4 , wherein

the additional inorganic barrier layers and the additional organic barrier layers are alternately laminated.

6. The organic light emitting diode display device of claim 1 , wherein

the groove pattern surrounds the organic light emitting diode.

7. The organic light emitting diode display device of claim 6 , wherein

the groove pattern has a quadrangular spiral shape.

8. The organic light emitting diode display device of claim 6 , wherein

the groove pattern is constituted by a plurality of quadrangles.

9. The organic light emitting diode display device of claim 6 , wherein

the groove pattern is constituted by a plurality of bars formed on the periphery of the substrate body.

10. The organic light emitting diode display device of claim 6 , wherein

a vertical cross-section of the groove pattern has an angled saw-tooth shape.

11. The organic light emitting diode display device of claim 6 , wherein

a vertical cross-section of the groove pattern has a curved saw-tooth shape.

12. The organic light emitting diode display device of claim 6 , wherein

the substrate body is flexible.

13. A method for manufacturing an organic light emitting diode display device, comprising:

preparing a substrate body that is divided into a display area and a neighboring area;

forming an organic light emitting diode within the display area of the substrate body;

forming a barrier film where one or more inorganic barrier layers and one or more organic barrier layers are alternately laminated, with the organic barrier layer disposed spaced apart from the substrate body by the inorganic barrier layer; and

attaching the inorganic barrier layer of the barrier film to the neighboring area of the substrate body by using an adhesive agent so that the barrier film covers the organic light emitting diode,

with a groove pattern being recessed on the surface of the inorganic barrier layer that is in contact with the adhesive agent.

14. The method of claim 13 , wherein

the substrate body is flexible.

15. The method of claim 13 , wherein

the groove pattern surrounds the organic light emitting diode.

16. The method of claim 15 , wherein

the groove pattern has a quadrangular spiral shape.

17. The method of claim 15 , wherein

the groove pattern is constituted by a plurality of quadrangles.

18. The method of claim 15 , wherein

the groove pattern is constituted by a plurality of bars formed on the periphery of the substrate body.

19. The method of claim 13 , wherein

a vertical cross-section of the groove pattern has an angled saw-tooth shape.

20. The method of claim 13 , wherein

a vertical cross-section of the groove pattern has a curved saw-tooth shape.
