Organic light-emitting display panel and manufacturing method thereof

The invention discloses an organic light-emitting display panel and a manufacturing method of the organic light-emitting display panel. The organic light-emitting display panel comprises an upper substrate, a first electrode layer, an organic light-emitting layer, a second electrode layer and a lower substrate, which are sequentially arranged, wherein a refraction layer is arranged on one side, deviating from the organic light-emitting layer, of the first electrode layer and comprises a plurality of convex bodies; each convex body is provided with a sharp corner, and the sharp corner faces the side deviating from the organic light-emitting layer. According to the technical scheme, through the refraction layer with the convex bodies, light emitted by the organic light-emitting layer can be effectively converged, and parallel light is formed within scope of each view angle, so that color offset of view angles is reduced.
