Abstract

An organic light-emitting display device includes a substrate, a plurality of pixel electrodes arranged in a matrix on the substrate, and an organic common layer covering the pixel electrodes. The pixel electrodes include a plurality of first pixel electrodes, a plurality of second pixel electrodes, and a plurality of third pixel electrodes. An n-th pixel column includes the second pixel electrodes; and the third pixel electrodes arranged alternately, an (n+1)-th pixel column which is adjacent to the n-th pixel column includes the first pixel electrodes, and an (n+2)-th pixel column which is adjacent to the (n+1)-th pixel column includes the second pixel electrodes and the third pixel electrodes arranged alternately, wherein n is a natural number. One of the second and third pixel electrodes is disposed in the n-th pixel column in a row and the other one of the second and third pixel electrodes is disposed in the (n+2)th pixel column in the same row.

Claims (20)

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

a substrate;

a plurality of pixel electrodes arranged in a matrix on the substrate, wherein the pixel electrodes comprise a plurality of first pixel electrodes, a plurality of second pixel electrodes, and a plurality of third pixel electrodes;

a first organic layer disposed on the first pixel electrode;

a second organic layer disposed on the second electrode; and

an organic common layer disposed on the first organic layer, the second organic layer and the third pixel electrodes; wherein

along an n-th pixel column, the first pixel electrodes and the second pixel electrodes are arranged alternately, and

along an (n+1)-th pixel column which is adjacent to the n-th pixel column, the third pixel electrodes are arranged repeatedly, wherein n is a natural number,

in regions of the organic common layer which overlaps the first pixel electrodes, the first organic layer emits green light and the organic common layer does not emit light,

in regions of the organic common layer which overlaps the second pixel electrodes, the second organic layer emits red light and the organic common layer does not emit light,

in regions of the organic common layer which overlaps the third pixel electrodes, the common organic layer emits blue light.

2. The display device of claim 1 , wherein a distance between each of the second pixel electrodes and one of the third pixel electrodes which neighbors the second pixel electrode is larger than a distance between each of the third pixel electrodes and one of the first pixel electrodes which neighbors the third pixel electrode in a row direction.

3. The display device of claim 1 , further comprising spacers formed on regions of the substrate between the second pixel electrodes and the third pixel electrodes.

4. The display device of claim 1 , further comprising spacers formed on regions of the substrate between the second pixel electrodes and the first pixel electrodes.

5. The display device of claim 1 , further comprising

first spacers formed on the regions of the substrate between the second pixel electrodes and the third pixel electrodes,

second spacers formed on the regions of the substrate between the second pixel electrodes and the first pixel electrodes, and

third spacers formed on the regions of the substrate between the third pixel electrodes and the first pixel electrodes.

6. The display device of claim 1 , further comprising a pixel defined layer disposed on the substrate and comprising a plurality of apertures arranged in a matrix,

wherein the pixel electrodes are formed in the apertures on the substrate.
