Organic light-emitting display device
An organic light-emitting display device includes pixels, a bank that defines the pixels and has at least one hollow portion formed between the pixels which neighbor each other, and a light stopper. At least part of the light stopper is inserted into the hollow portion.
1. An organic light-emitting display device comprising:
pixels:
a bank that defines the pixels and has at least one hollow portion formed between the pixels which neighbor each other;
a light stopper that blocks or absorbs light incident on the light stopper, at least part of which is inserted into the at least one hollow portion; and
a barrier surrounding the light stopper,
wherein the barrier is divided into a first portion and a second portion, and
wherein the first portion and the second portion are made of different materials.
2. The organic light-emitting display device of claim 1 , wherein a top surface of the light stopper is spaced a preset distance apart from a top surface of the bank.
3. The organic light-emitting display device of claim 1 , wherein the at least one hollow portion has a shape of a recess formed by partially recessing a top surface of the bank inward.
4. The organic light-emitting display device of claim 1 , wherein the light stopper is disposed between pixels that emit light of different colors.
5. The organic light-emitting display device of claim 1 , wherein the pixels comprise:
a first pixel that emits light of a first color;
a second pixel that neighbors the first pixel in a first direction and emits light of a second color; and
a third pixel that neighbors the first pixel in a second direction and emits light of the first color,
wherein the light stopper is situated between the first pixel and the second pixel but not between the first pixel and the third pixel.
6. The organic light-emitting display device of claim 1 , further comprising:
first electrodes allocated individually to the pixels;
an organic compound layer disposed on the first electrodes and covering the first electrodes; and
a second electrode disposed on the organic compound layer and covering the organic compound layer,
wherein the organic compound layer is physically separated on the bank in at least one region where the light stopper is placed.
7. The organic light-emitting display device of claim 6 , wherein the second electrode is physically separated on the bank in the at least one region.
8. The organic light-emitting display device of claim 1 , wherein the barrier includes an inorganic material.
9. The organic light-emitting display device of claim 1 , wherein the light stopper is black in color.
