Abstract

An organic light-emitting display device includes a pixel electrode, an emission layer on the pixel electrode, an opposing electrode covering the emission layer, a plurality of upper layers on the opposing electrode, light-shielding elements on the upper layers, and a color filter layer on the upper layers. The light-shielding elements include first light-shielding layers and second light-shielding layers. The first light-shielding layers include first materials, and the second light-shielding layers include second materials different from the first materials. The second light-shielding layers overlay the first light-shielding layers.

Claims (49)

1. An organic light-emitting display device, comprising:

a pixel electrode;

an emission layer on the pixel electrode;

an opposing electrode covering the emission layer;

a plurality of upper layers on the opposing electrode;

light-shielding elements on the upper layers; and

a color filter layer on the upper layers,

wherein:

each of the light-shielding elements includes a first light-shielding layer including first materials and a second light-shielding layer including second materials different from the first materials,

the first materials are or include organic materials,

the second materials are or include metal materials, and

a first thickness of the first light-shielding layers is greater than a second thickness of the second light-shielding layers, the second thickness being in a range of from 200 Å to 500 Å.

2. The organic light-emitting display device as claimed in claim 1 , wherein:

a width of the second light-shielding layers is greater than a width of the first light-shielding layers.

3. The organic light-emitting display device as claimed in claim 1 , wherein:

the second light-shielding layers directly contact the first light-shielding layers.

4. An organic light-emitting display device, comprising:

a pixel electrode;

an emission layer on the pixel electrode;

an opposing electrode covering the emission layer;

a plurality of upper layers on the opposing electrode;

light-shielding elements on the upper layers; and

a color filter layer on the upper layers,

wherein:

the light-shielding elements include first light-shielding layers and second light-shielding layers,

the first light-shielding layers include first materials,

the second light-shielding layers include second materials different from the first materials, the second light-shielding layers overlying the first light-shielding layers, and

widths of the second light-shielding layers are greater than widths of the first light-shielding layers, the second light-shielding layers are farther from the pixel electrode than the first light-shielding layers.

5. The organic light-emitting display device as claimed in claim 4 , wherein:

the ends of edges of the second light-shielding layers and the ends of edges of the first light-shielding layers are on a same surface.

6. The organic light-emitting display device as claimed in claim 4 , wherein:

a thickness of the second light-shielding layers is greater than a thickness of the first light-shielding layers.

7. The organic light-emitting display device as claimed in claim 4 , wherein:

a thickness of the first light-shielding layer is in a range of from about 200 Å to about 500 Å.

8. The organic light-emitting display device as claimed in claim 4 , wherein:

the second light-shielding layers directly contact the first light-shielding layers.

9. The organic light-emitting display device as claimed in claim 4 , wherein:

the first materials are or include metal materials.

10. The organic light-emitting display device as claimed in claim 9 , wherein:

the second materials are or include organic materials.

11. The organic light-emitting display device as claimed in claim 4 , further comprising:

a pixel defining layer covering edges of the pixel electrode such that a center area of the pixel electrode is exposed,

wherein the upper layers correspond to the pixel electrode and the pixel defining layer.

12. The organic light-emitting display device as claimed in claim 11 , wherein:

ends of edges of the second light-shielding layers are between ends of edges of the first light-shielding layers and ends of edges of the pixel defining layer.

13. The organic light-emitting display device as claimed in claim 11 , wherein:

a light-emitting area of the emission layer corresponds to an area of the pixel electrode not covered by the pixel defining layer.

14. The organic light-emitting display device as claimed in claim 13 , wherein:

a first distance between one of the first light-shielding layers and another one of the first light-shielding layers adjacent thereto is greater than a width of the light-emitting area.
