Abrégé
(EN)
The invention discloses an organic light emitting display panel and a display device. The organic light emitting display panel comprises a substrate, an organic light emitting device and a cap layer, wherein the organic light emitting device is arranged on the substrate; the cap layer is arranged at the side far away from the substrate of the organic light emitting device; the cap layer comprises scattering particles; and a scattering micro-structure is arranged on the surface far away from the organic light emitting device of the cap layer. According to the organic light emitting display panel and the display device which are provided by the invention, the scattering particles and the scattering micro-structure are simultaneously arranged on the cap layer, and the light is emergent to each direction on the surface of the organic light emitting display panel through the combined action of two structures, so that the scattered light can be seen from all angles of the organic light emitting display panel, the view color cast phenomenon is improved, and meanwhile, the total reflection of the light can be reduced through the scattered particles, the optical loss is reduced and the light output rate is improved, and thus the luminous efficiency of the OLED device is improved.
