Abstract

The present invention relates to an organic light emitting device and a method of preparing the same. More particularly, the organic light emitting device according to the present invention includes: a substrate; an organic light emitting unit in which a first electrode, an organic material layer, and a second electrode are sequentially stacked on the substrate; and an encapsulating unit configured to seal an external side of the organic light emitting unit, in which a protecting unit is provided on at least a partial region of the substrate, on which the organic light emitting unit and the encapsulating unit are not provided, and at least a partial region in a lateral surface region of the substrate.

First claim

1 . An organic light emitting device, comprising:
a substrate; an organic light emitting unit in which a first electrode, an organic material layer, and a second electrode are sequentially stacked on the substrate; and an encapsulating unit configured to seal an external side of the organic light emitting unit, wherein a protecting unit is provided on at least a partial region of the substrate, on which the organic light emitting unit and the encapsulating unit are not provided, and at least a partial region in a lateral surface region of the substrate.

2 . The organic light emitting device of claim 1 , wherein the substrate is a thin glass substrate.

3 . The organic light emitting device of claim 2 , wherein a thickness of the thin glass substrate is 0.1 mm or lower.

4 . The organic light emitting device of claim 1 , wherein the protecting unit is provided over an region of the substrate, on which the organic light emitting unit and the encapsulating unit are not provided, and an entire region of the lateral surface region of the substrate.

5 . The organic light emitting device of claim 4 , wherein the protecting unit is additionally provided over an entire region of an upper region and a lateral surface region of the encapsulating unit.

6 . The organic light emitting device of claim 1 , wherein an out coupling film (OCF) having a wider area than that of the substrate is additionally provided under the substrate.

7 . The organic light emitting device of claim 6 , wherein the substrate having a smaller area than that of the OCF is provided on the OCF, and
the protecting unit is additionally included on a region of the OCF on which the substrate is not provided.

8 . The organic light emitting device of claim 1 , wherein the protecting unit comprises a plastic film.

9 . The organic light emitting device of claim 1 , wherein the protecting unit comprises an insulating layer and a metal pattern layer.

10 . The organic light emitting device of claim 9 , wherein the protecting unit comprises two-layered insulating layer and a metal pattern layer provided between the two-layered insulating layer.

11 . The organic light emitting device of claim 9 , wherein the first electrode or the second electrode is electrically connected with an external power source through the metal pattern layer.

12 . The organic light emitting device of claim 9 , wherein the metal pattern layer comprises a first metal pattern for electrically connecting the first electrode and an external power source.

13 . The organic light emitting device of claim 9 , wherein the metal pattern layer comprises a second metal pattern for electrically connecting the second electrode and an external power source.

14 . The organic light emitting device of claim 1 , wherein the encapsulating unit comprises a sealing layer which is in contact with an external side of the organic light emitting unit, and a metal layer provided on the sealing layer.

15 . The organic light emitting device of claim 1 , wherein the organic light emitting device is a flexible organic light emitting device.

16 . The organic light emitting device of claim 1 , further comprising:
a light extracting layer between the substrate and the first electrode.

17 . The organic light emitting device of claim 16 , further comprising:
a flattening layer on the light extracting layer.

18 . A lighting device comprising the organic light emitting device of claim 1 .

19 . A display device comprising the organic light emitting device of claim 1 .
