THIN FILM TRANSISTOR ARRAY PANEL AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A thin film transistor display plate and a manufacturing method thereof are provided to reduce resistance by selectively making a signal line thick. CONSTITUTION: A gate wire is located on a substrate. The wire includes a gate line(121) and a gate electrode(124). The gate line is horizontally extended. The gate electrode protrudes from the gate line. A data line(171) is located on the substrate and vertically extended. An interlayer insulating film is located on the gate wire and the data line. A semiconductor layer(154) is located on the interlayer insulating film. A drain electrode(175) is located on a source electrode(173) and a gate electrode is located on a spot opposite to the source electrode. The source electrode is located on the semiconductor layer. A protective film is located on the source electrode and the drain electrode. A pixel electrode(191) locates on the protective film.
