Abstract
The embodiments of the present application disclose an organic light emitting display panel and a manufacturing method thereof. The organic light emitting display panel includes an organic light emitting diode layer and a metal nanoparticle layer. The metal nanoparticle layer is disposed on a side of the organic light emitting diode layer in contact with external environment, wherein metal nanoparticles of the metal nanoparticle layer can use their own surface plasmon resonance absorption effect to absorb ultraviolet rays emitted from external environment to the organic light emitting diode layer, thereby preventing ultraviolet rays from irradiating the organic light emitting diode layer.
