Abstract

An organic light-emitting device includes a substrate; an encapsulation substrate; an organic light-emitting unit interposed between the substrate and the encapsulation substrate; and a layer having an UV shielding capability interposed between the encapsulation substrate and the organic light-emitting unit.

Claims

1. An organic light-emitting device comprising:

a substrate;

an encapsulation substrate;

an organic light-emitting unit interposed between the substrate and the encapsulation substrate; and

a layer having an ultraviolet (UV) shielding capability interposed between the encapsulation substrate and the organic light-emitting unit.

3. The organic light-emitting device of claim 1, wherein the layer contacts a surface of the encapsulation substrate.

4. The organic light-emitting device of claim 1, wherein the layer contacts a surface of the organic light-emitting unit.

5. The organic light-emitting device of claim 1, wherein the layer is spaced apart from both the encapsulation substrate and the:

organic light-emitting unit.

6. The organic light-emitting device of claim 1, wherein the layer contacts a surface of the encapsulation substrate, and

the surface of the encapsulation substrate has a cavity structure or a trench structure formed by etching.

7. The organic light-emitting device of claim 1, wherein an adhesive is applied to the layer and the total thickness of the formed adhesive layer and the layer is in a range of about 20 μ

m to about 100 μ

m.

9. The organic light-emitting device of claim 1, wherein an anti-reflection coating film is further formed on the encapsulation substrate.

2. The organic light-emitting device of claim wherein the layer further comprises a polarizing capability.

8. The organic light-emitting device of claim 2, wherein an adhesive is applied to the layer having an UV shielding capability and a polarizing capability, and the total thickness of the formed adhesive layer and the layer is in a range of about 220 μ

m to about 300 μ

m.
