Abstract

An organic light-emitting display apparatus includes: a display substrate; a plurality of organic light-emitting diodes (OLEDs) on the display substrate, the OLEDs being divided from one another by a pixel defining layer (PDL); an encapsulation substrate on the display substrate and covering the OLEDs; a filling material on the PDL and between the display substrate and the encapsulation substrate; and a cavity between the OLEDs and the encapsulation substrate.

Claims (30)

1. An organic light-emitting display apparatus comprising:

a display substrate;

a plurality of organic light-emitting diodes (OLEDs) on the display substrate, the OLEDs being divided from one another by a pixel defining layer (PDL);

an encapsulation substrate on the display substrate and covering the OLEDs;

a black matrix between the PDL and the encapsulation substrate, the black matrix being on the encapsulation substrate;

a filling material only on the PDL and between the display substrate and the encapsulation substrate, the filling material contacting the black matrix and the PDL; and

a cavity between the OLEDs and the encapsulation substrate.

2. The organic light-emitting display apparatus of claim 1 , further comprising a color filter between the OLEDs and the encapsulation substrate.

3. The organic light-emitting display apparatus of claim 2 , wherein a wavelength of light passed by the color filter corresponds to a wavelength area of light emitted from an OLED of the OLEDs corresponding to the color filter.

4. The organic light-emitting display apparatus of claim 1 , wherein the black matrix comprises one of Cr, CrO, graphite, and C.

5. The organic light-emitting display apparatus of claim 1 , wherein the cavity is filled with air or nitrogen (N 2 ) gas.

6. The organic light-emitting display apparatus of claim 1 , further comprising a protective layer on the OLEDs.

7. The organic light-emitting display apparatus of claim 1 , further comprising a conductive layer between the filling material and the OLEDs to electrically contact a cathode electrode of the OLEDs,

wherein the cathode electrode is between the PDL and the filling material.

8. The organic light-emitting display apparatus of claim 1 , further comprising an encapsulation material adhered to the display substrate and to the encapsulation substrate and enclosing the plurality of OLEDs.

9. The organic light-emitting display apparatus of claim 1 , further comprising an absorbent adjacent the plurality of OLEDs and contacting an encapsulation material.

10. An organic light-emitting display apparatus comprising:

a display substrate;

a display on the display substrate and comprising a plurality of light-emission areas comprising a plurality of organic light emitting diodes (OLEDs) and a non-light-emission area between adjacent ones of the light-emission areas;

an encapsulation substrate facing the display substrate;

a black matrix in the non-light-emission area, the black matrix being on the encapsulation substrate;

a color filter in the light-emission areas; and

a filling material between the display substrate and the encapsulation substrate and disposed only in the non-light-emission area, the filling material contacting the black matrix and the non-light-emission area of the display.

11. The organic light-emitting display apparatus of claim 10 , wherein the non-light-emission area protrudes from the display substrate more than the light-emission areas protrude from the display substrate.

12. The organic light-emitting display apparatus of claim 10 , wherein the filling material is an insulating material.

13. The organic light-emitting display apparatus of claim 10 , further comprising a conductive layer between the non-light-emission area and the filling material and electrically connected to cathode electrodes of the OLEDs.

14. The organic light-emitting display apparatus of claim 10 , further comprising a protective layer on the OLEDs.

15. The organic light-emitting display apparatus of claim 10 , further comprising:

an encapsulation material adhered to the display substrate and to the encapsulation substrate; and

an absorbent adjacent the plurality of OLEDs and contacting the encapsulation material.
