An organic light emitting display panel includes a substrate having one or more organic light emitting diodes thereon; a pixel definition layer, wherein the pixel definition layer defines one or more sub-pixel regions on the substrate; a metal layer, wherein the metal layer is located on one side of the pixel definition layer away from the substrate; an anti-reflection layer, wherein the anti-reflection layer is located on one side of the metal layer away from the pixel definition layer, and the orthographic projection of the metal layer on the substrate is located within the range where the orthographic projection of the anti-reflection layer on the substrate is located; a light emitting layer, wherein the light emitting layer is located on one side of the anti-reflection layer away from the metal layer; and a cathode, wherein the cathode is located on one side of the light emitting layer away from the anti-reflection layer, and the cathode is connected to the metal layer in a roundabout manner.
