Abstract
An organic light emitting display device is capable of substantially preventing the occurrence of color mixture and improve the color purity, the organic light emitting display device including: a substrate; a first electrode on the substrate; a pixel defining layer defining a first opening which exposes at least a portion of the first electrode; a first organic light emission layer on the first electrode; and a second electrode on the first organic light emission layer, wherein the pixel defining layer may include quantum dots.
Claims20
An organic light emitting display device, comprising:
- a substrate;
- a first electrode on the substrate;
- a pixel defining layer defining a first opening that exposes at least a portion of the first electrode;
- a first organic light emission layer on the first electrode in the first opening, the first organic light-emission layer to emit light of a first color;
- and
- a second electrode on the first organic light emission layer, wherein the pixel defining layer adjacent to the first opening includes quantum dots that emit light of a color that is substantially the same as the first color.
A display device, comprising:
- a substrate;
- a first electrode and a second electrode on the substrate;
- and
- a first pixel including an organic emission layer to emit light of a first color, a second pixel including an organic emission layer to emit light of a second color, and a third pixel including an organic emission layer to emit light of a third color, the first, second, and third colors being different from each other, wherein
- a pixel defining layer adjacent to the first pixel includes quantum dots that emit light of the first color, a pixel defining layer adjacent to the second pixel includes quantum dots that emit light of the second color, and a pixel defining layer adjacent to the third pixel includes quantum dots that emit light of the third color.
