Abstract
An organic light emitting display includes a substrate, an organic light emitting device on the substrate, the organic light emitting device including a first electrode, an organic emitting layer, and a second electrode, a UV light shielding layer having at least two layers, each layer absorbing different wavelengths of UV light, and an encapsulation layer sealing the organic light emitting device.
Claims15
An organic light emitting display, comprising:
- a substrate;
- an organic light emitting device on the substrate, the organic light emitting device including a first electrode, an organic emitting layer, and a second electrode;
- a UV light shielding layer on the organic light emitting device, the UV light shielding layer including at least a first UV light shielding layer and a second UV light shielding layer sequentially stacked on the organic light emitting device, the first and second UV light shielding layers being discrete layers, and the first UV light shielding layer absorbing a first wavelength of UV light and the second UV light shielding layer absorbing a different second wavelength of UV light, the first wavelength being longer than the second wavelength;
- and
- an encapsulation layer on the UV light shielding layer sealing the organic light emitting device.
