Abstract

An organic light emitting display device including: a substrate; a sealing member; an organic light emitting device between the substrate and the sealing member and for displaying images; a selective light absorbing layer on a surface of the sealing member facing the organic light emitting device and including pigments for selectively absorbing light; and a black matrix layer on the selective light absorbing layer corresponding to non-emission areas of the organic light emitting device.

Claims (27)

1. An organic light emitting display device comprising:

a substrate;

a sealing member;

an organic light emitting device between the substrate and the sealing member and for displaying images;

a selective light absorbing layer on a surface of the sealing member facing the organic light emitting device and comprising pigments for selectively absorbing light;

a reflection preventive layer on at least one surface of the sealing member; and

a black matrix layer on the selective light absorbing layer and corresponding to non-emission areas of the organic light emitting device.

2. The organic light emitting display device of claim 1 , wherein the organic light emitting device comprises:

a first electrode,

a pixel define layer on the first electrode and having an opening for exposing the first electrode,

an organic light emitting layer on the first electrode exposed by the opening, and

a second electrode on the organic light emitting layer,

wherein the black matrix layer is on the selective light absorbing layer and corresponding to the pixel define layer of the organic light emitting device.

3. The organic light emitting display device of claim 1 , wherein the selective light absorbing layer comprises a red pigment and a blue pigment.

4. The organic light emitting display device of claim 1 , wherein the selective light absorbing layer has an optical transmittance ranging from about 10 to about 90% at a wavelength of about 550 nm.

5. The organic light emitting display device of claim 1 , wherein the black matrix layer has a thickness ranging from about 5 to about 20 μm.

6. The organic light emitting display device of claim 1 , wherein the black matrix layer comprises a material selected from the group consisting of carbon black particles and graphite.

7. The organic light emitting display device of claim 1 , wherein the reflection preventive layer comprises:

a semi-transparent film for transmitting a portion of an external light and for reflecting another portion of the external light, and

a protective film covering the semi-transparent film,

wherein the semi-transparent film has a refractive index greater than that of the protective film.

8. The organic light emitting display device of claim 7 , wherein the semi-transparent film comprises a material selected from the group consisting of Au, Ag, and Ti.

9. The organic light emitting display device of claim 7 , wherein the protective film comprises a thermosetting resin.

10. The organic light emitting display device of claim 7 , wherein the protective film comprises a material selected from the group consisting of urethane acrylate and epoxy resin.

11. The organic light emitting display device of claim 7 , wherein the semi-transparent film has an optical transmittance ranging from about 40 to about 80%.

12. The organic light emitting display device of claim 7 , wherein the semi-transparent film has a refractive index ranging from about 1.5 to about 5.

13. The organic light emitting display device of claim 7 , wherein the semi-transparent film is a metal colloid.
