Abstract
A method for fabricating an organic light emitting display panel includes: forming an anode-material layer on a base plate, forming a mask on one side of the anode-material layer away from the base plate, and performing patterning treatment to the anode-material layer by using the mask, to form multiple anodes; and forming a pixel definition layer covering the mask and the base plate, and performing patterning treatment to the pixel definition layer and the mask at the same time, to form a multiple pixel defining components, wherein the pixel defining components cover parts of the base plate located between two neighboring anodes, and cover part of surfaces of the anodes; and a material forming the mask and a material forming the pixel definition layer are the same, each of the pixel defining components includes a first part formed by the mask, and a second part formed by the pixel definition layer.
