Organic light emitting display device and method for fabricating the same
An OLED device includes a substrate including first through fourth sub-pixel regions arranged in a quad type, a first electrode disposed on each of the first through fourth sub-pixel regions, a first functional layer disposed on all the first through fourth sub-pixel regions and configured to emit first color light, a second functional layer formed in a stripe shape, which progresses along the second and fourth sub-pixel regions arranged in a row direction, and configured to emit second color light, a third functional layer formed in another stripe shape, which progresses along the third and fourth sub-pixel regions arranged in a column direction, and configured to emit third color light, and a second electrode disposed on the entire surface of the substrate including the first through third functional layers.
1. An organic light emitting display device comprising:
a substrate including first through fourth sub-pixel regions arranged in a quad type;
a first electrode disposed on each of the first through fourth sub-pixel regions;
a first functional layer disposed on all the first through fourth sub-pixel regions and configured to emit first color light;
a second functional layer formed in a stripe shape, which progresses along the second and fourth sub-pixel regions arranged in a row direction, and configured to emit second color light;
a third functional layer formed in another stripe shape, which progresses along the third and fourth sub-pixel regions arranged in a column direction, and configured to emit third color light;
a second electrode disposed on the entire surface of the substrate including the first through third functional layers; and
an electrical charge generation layer disposed under the first functional layer.
2. The organic light emitting display device of claim 1 , wherein the first sub-pixel region is formed with a larger dimension than those of the second through fourth sub-pixel regions.
3. The organic light emitting display device of claim 2 , wherein the second and third functional layers are each formed in a rectangular shape and cross each other.
4. The organic light emitting display device of claim 2 , wherein the first through third functional layers overlap one another in the fourth sub-pixel region so that the fourth sub-pixel region is able to display a white color.
5. The organic light emitting display device of claim 1 , further comprising:
a first sub-functional layer configured to emit the first color light; and
the electrical charge generation layer disposed on the first sub-functional layer.
6. The organic light emitting display device of claim 1 , further comprising:
first through third sub-functional layers formed in the same structure as the first through third functional layers.
7. The organic light emitting display device of claim 1 , wherein the first color light is blue light.
8. The organic light emitting display device of claim 5 , further comprising:
at least one of a sub hole injection layer and a sub hole transport layer that are interposed between the first electrode and the first sub-functional layer.
9. The organic light emitting display device of claim 6 , further comprising:
at least one of a sub hole injection layer and a sub hole transport layer that are interposed between the first electrode and the first sub-functional layer.
10. The organic light emitting display device of claim 5 , wherein the electrical charge generation layer includes an N-type electrical-charge generation layer and a P-type electrical-charge generation layer.
