摘要:
A method of manufacturing a thin film transistor matrix substrate is provided. The first photo-mask process is used to define a gate electrode and a signal electrode. The second photo-mask process is used to obtain different thickness of a PR layer in different regions for forming a channel, gate electrode through holes, signal electrode through holes and conductive pads. The third photo-mask process is used to define a source, a drain, an upper signal electrode, a pixel electrode, gate electrode pads and signal electrode pads.
