Abstract

An organic light emitting display according to an exemplary embodiment of the present invention includes a first pixel to represent a white color, a second pixel to represent a different color from the first pixel, a pixel electrode disposed in each of the first and the second pixels, an organic light emitting member disposed on the pixel electrode, and a common electrode disposed on the organic light emitting member. The first pixel includes a first emission area and a first optical filter, and the second pixel includes a second emission area and a second optical filter.

Claims (41)

1. An organic light emitting display, comprising:

a first pixel to represent a white color, comprising a first emission area;

a second pixel to represent a color different from the first pixel, comprising a second emission area;

a pixel electrode disposed in each of the first pixel and the second pixel;

an organic light emitting member disposed on the pixel electrodes;

a common electrode disposed on the organic light emitting member;

a semi-light blocking member disposed in the first emission area; and

a color filter disposed in the second emission area; and

a light blocking member disposed outside the first emission area and outside the second emission area,

wherein the semi-light blocking member is disposed on the same layer as the light blocking member and is thinner than the light blocking member.

2. The organic light emitting display of claim 1 , wherein an edge of the semi-light blocking member adjoins an edge of the light blocking member.

3. The organic light emitting display of claim 2 , wherein the semi-light blocking member comprises the same material as the light blocking member.

4. The organic light emitting display of claim 3 , wherein the semi-light blocking member comprises one of CrOx/Cr and NiOx/Ni.

5. The organic light emitting display of claim 4 , wherein the semi-light blocking member is disposed under the organic light emitting member.

6. The organic light emitting display of claim 4 , wherein the semi-light blocking member is disposed on the organic light emitting member.

7. The organic light emitting display of claim 4 , wherein the semi-light blocking member has a thickness of 4 nm to 20 nm.

8. The organic light emitting display of claim 1 , wherein a portion of the color filter is disposed outside the second emission area.

9. The organic light emitting display of claim 8 , wherein the color filter overlaps with a portion of the light blocking member.

10. The organic light emitting display of claim 9 , wherein the color filter comprises one of a red filter, a green filter, and a blue filter, and the organic light emitting member comprises a white organic light emitting member.

11. The organic light emitting display of claim 10 , wherein the color filter is disposed under the organic light emitting member.

12. The organic light emitting display of claim 11 , wherein the light blocking member is disposed under the organic light emitting member.

13. The organic light emitting display of claim 10 , wherein the color filter is disposed on the organic light emitting member.

14. The organic light emitting display of claim 13 , wherein the light blocking member is disposed on the organic light emitting member.

15. An organic light emitting display, comprising:

a substrate;

a light blocking member with an opening disposed on the substrate;

a semi-light blocking member that is part of the same layer as the light blocking member, the semi-light blocking member being thinner than the light blocking member;

a color filter disposed in the area corresponding to the opening in the light blocking member;

a pixel electrode disposed on the color filter;

a white organic light emitting member disposed on the pixel electrode; and

a common electrode disposed on the organic light emitting member.

16. The organic light emitting display of claim 15 , wherein light emitted from the organic light emitting member penetrates through the color filter to represent one of red, green, and blue light and through the semi-light blocking member to represent white light.

17. An organic light emitting display, comprising:

a first substrate;

a pixel electrode disposed on the first substrate;

a white organic light emitting member disposed on the pixel electrode;

a common electrode disposed on the white organic light emitting member;

a color filter disposed on the common electrode;

a light blocking member disposed on the common electrode and comprising an opening that faces the color filter;

a semi-light blocking member that is part of the same layer as the light blocking member, the semi-light blocking layer being thinner than the light blocking member; and

a second substrate disposed on the light blocking member and the semi-light blocking member.
