Abstract

An organic light emitting device is provided. The device may include a substrate having an emission region and a non-emission region, a sub-pixel formed on the substrate in the emission region of the substrate, and a sealant provided in the non-emission region that seals the emission region of the substrate. The sub-pixel may include a first electrode formed on the substrate in the emission region of the substrate, an emission portion formed on the first electrode, and a second electrode arranged on the emission portion. A barrier rib may be provided to partition the second electrode. A width of an end portion of the barrier rib may be narrower than a width of another portion of the barrier rib.

Claims (18)

1. An organic light emitting display, comprising:

a first electrode arranged on a substrate;

an emission portion formed on the first electrode;

a second electrode arranged on the emission portion;

a barrier rib partitioning the second electrode, the barrier rib formed so that an end portion of the barrier rib has a narrower width than another portion of the barrier rib; and

a sealant formed to seal the emission portion.

2. The organic light emitting display of claim 1 , wherein the end portion of the barrier rib has a lower height than the another portion of the barrier rib.

3. The organic light emitting display of claim 1 , further comprising a barrier partitioning the barrier rib from the sealant.

4. The organic light emitting display of claim 1 , wherein a length of the end portion of the barrier rib is 100 μm or less.

5. The organic light emitting display of claim 1 , wherein the emission portion includes an organic light emitting layer.

6. The organic light emitting display of claim 1 , wherein a cross section of the end portion of the barrier rib taken in a height direction thereof has an exterior angle slope of 90 degrees or more.

7. The organic light emitting display of claim 2 , further comprising a barrier that partitions the barrier rib from the sealant.

8. The organic light emitting display of claim 2 , wherein a length of the end portion of the barrier rib is 100 μm or less.

9. The organic light emitting display of claim 2 , wherein the emission portion includes an organic light emitting layer.

10. The organic light emitting display of claim 2 , wherein a cross section of the end portion of the barrier rib taken in a height direction thereof has an exterior angle slope of 90 degrees or more.

11. The organic light emitting display of claim 6 , further comprising a barrier that partitions the barrier rib from the sealant.

12. The organic light emitting display of claim 6 , wherein a length of the end portion of the barrier rib is 100 μm or less.

13. The organic light emitting display of claim 6 , wherein the emission portion includes an organic light emitting layer.
