Abstract

An organic light-emitting display apparatus includes: an organic light-emitting device including a plurality of sub-pixels respectively emitting lights of different colors; a color filter formed on the organic light-emitting device in a region corresponding to each of the sub-pixels; a spacer color filter formed in the color filter between red, green, and blue color filters at locations corresponding to non-emitting areas; and a substrate provided on the color filter to encapsulate the organic light-emitting device.

Claims (36)

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

an organic light-emitting device comprising a plurality of sub-pixels, the sub-pixels configured to emit lights of different colors;

a spacer color filter disposed in a non-light emitting area directly bound by the red color filter and the green color filter in the same plane, the spacer color filter comprising a material different from the red color filter and green color filter; and

a substrate disposed on the color filter and encapsulating the organic light-emitting device.

2. The organic light-emitting display apparatus of claim 1 , wherein the color filter further comprises a blue color filter and the spacer color filter comprises a first layer comprising the same material as the blue color filter.

3. The organic light-emitting display apparatus of claim 2 , wherein the spacer color filter further comprises a second layer stacked on the first layer, and the second layer comprises the same material as the red color filter.

4. The organic light-emitting display apparatus of claim 2 , wherein the spacer color filter further comprises second and third layers stacked on the first layer, wherein the second layer comprises the same material as the green color filter and the third layer comprises the same material as the red color filter.

5. The organic light-emitting display apparatus of claim 1 , further comprising an intermediate layer disposed between the color filter and the substrate and having a refractive index between a refractive index of the color filter and a refractive index of the substrate.

6. The organic light-emitting display apparatus of claim 5 , wherein the color filter further comprises a blue color filter and the spacer color filter comprises stacked first and second layers, the first layer comprising the same material as the blue color filter and the second layer comprising the same material as the red color filter.

7. The organic light-emitting display apparatus of claim 5 , wherein the color filter further comprises a blue color filter and the spacer color filter comprises sequentially stacked first, second, and third layers, the first layer comprising the same material as the blue color filter, the second layer comprising the same material as the green color filter, and the third layer comprising the same material as the red color filter.

8. The organic light-emitting display apparatus of claim 5 ,
