Abstract

Provided is an organic light emitting display apparatus in which process efficiency and contrast are increased. The organic light emitting display apparatus includes a substrate, a display unit that is formed on the substrate and includes an organic light emitting device, an encapsulation layer that is formed on the display unit so as to encapsulate the display unit, a color filter layer that is formed on the encapsulation layer, a protection layer that is formed on the color filter layer, and a black matrix that is formed on the protection layer. The black matrix is aligned not to overlap the color filter layer.

Claims

1. An organic light emitting display apparatus comprising:

a substrate;

a display unit formed on the substrate, the display unit comprising an organic light emitting device for emitting light;

an encapsulation layer formed on the display unit so as to encapsulate the display unit;

a color filter layer formed on the encapsulation layer;

a protection layer formed on the color filter layer; and

a black matrix formed on the protection layer.

2. The organic light emitting display apparatus of claim 1, wherein the protection layer is formed to cover the color filter layer.

3. The organic light emitting display apparatus of claim 1, wherein the protection layer is made of a material including an inorganic material.

4. The organic light emitting display apparatus of claim 1, wherein the protection layer is made of a material including one material selected from the group consisting of calcium oxide, alumina, silica, titania, indium oxide, tin oxide, silicon oxide, silicon nitride, aluminum nitride, and combinations thereof.

5. The organic light emitting display apparatus of claim 1, further comprising a cover layer formed on the black matrix.

6. The organic light emitting display apparatus of claim 5, wherein the cover layer is formed to cover the black matrix and the protection layer.

7. The organic light emitting display apparatus of claim 5, wherein the cover layer is made of a material including an inorganic material.

8. The organic light emitting display apparatus of claim 5, wherein the cover layer is made of a material including one material selected from the group consisting of calcium oxide, alumina, silica, titania, indium oxide, tin oxide, silicon oxide, silicon nitride, aluminum nitride, and combinations thereof.

9. The organic light emitting display apparatus of claim 1, wherein the black matrix is aligned not to overlap with the color filter layer.

10. The organic light emitting display apparatus of claim 1, wherein the color filter layer comprising a first color filter, a second color filter, and a third color filter, the black matrix is aligned not to overlap with each of the first color filter, the second color filter, and the third color filter.

11. The organic light emitting display apparatus of claim 1, wherein the display unit comprises a first intermediate layer, a second intermediate layer, and a third intermediate layer for emitting light.

12. The organic light emitting display apparatus of claim 11, wherein each of the first intermediate layer, the second intermediate layer, and the third intermediate layer emits light with the same color.

13. The organic light emitting display apparatus of claim 12, wherein the color filter comprising:

a first color filter disposed to overlap with the first intermediate layer;

a second color filter disposed to overlap with the second intermediate layer; and

a third color filter disposed to overlap with the third intermediate layer, the first color filer, the second color filter, and the third color filter having different colors from each other.
