Abstract
The present invention relates to a method of manufacturing an organic light emitting display panel. The method includes forming a light shielding layer on a substrate, forming a first oxide semiconductor and a second oxide semiconductor on the light shielding layer, and forming a gate insulating layer and a gate overlapping a portion of the first oxide semiconductor and a whole of the second oxide semiconductor. The method further includes performing an etching so that the portion of the first oxide semiconductor has conductivity, forming a first contact hole in the light shielding layer and forming a second contact hole in the first oxide semiconductor, forming a driving power line connected to the light shielding layer through the first contact hole, and forming source/drain electrodes connected to the first oxide semiconductor through the second contact hole.
