Abstract:
1. A method for manufacturing an organic light emitting diode display, the method comprising: forming a first storage plate of a polysilicon layer; forming a gate insulating layer covering the first storage plate on a substrate; sequentially forming a second storage plate for covering the first storage plate and a capacitor intermediate on the gate insulating layer; forming a first doping region by injecting an impurity to a part that is not covered by the capacitor intermediate in the first storage plate; forming an interlayer insulating layer having a capacitor opening exposing the capacitor intermediate, the interlayer insulating layer having a plurality of erosion preventing layers on an edge of the capacitor intermediate toward the first doping region in the capacitor opening; removing the capacitor intermediate, including the erosion preventing layer and a lower region of the erosion preventing layer; and injecting an impurity in the first storage plate through the second storage plate to form a second doping region contacting the first doping region.
