Abstract:
1. A method of manufacturing an organic light emitting diode display, comprising: forming an amorphous silicon layer on a substrate; forming a gate insulating layer on the amorphous silicon layer; forming a gate electrode on the gate insulating layer; crystallizing and doping the amorphous silicon layer, to form a semiconductor layer having a channel region, a source region, and a drain region; forming an interlayer insulating layer on the gate electrode; forming contact holes in the interlayer insulating layer and the gate insulating layer, to expose the source and the drain regions; forming a first conductive layer on the interlayer insulating layer, such that the first conductive layer contacts the source and drain regions of the semiconductor layer, through the contact holes; forming a second conductive layer on the first conductive layer; patterning the first and second conductive layers through photolithography, to form source and drain electrodes, and patterning the second conductive layer to form a pixel electrode, wherein the source and drain electrodes are double-layered structures and the pixel electrode is a single-layered structure.
