THIN FILM TRANSISTOR SUBSTRATE AND METHOD OF MANUFACTURING THE SAME

摘要

PURPOSE: A thin film transistor substrate and a manufacturing method thereof are provided to improve a device property of a thin film transistor by preventing the deterioration of a surface roughness in a gate electrode. CONSTITUTION: A pixel region is defined by alternatively arranging a gate line(200) and a data line(500) on a substrate(100). A gate electrode(220) is connected to the gate line. A source electrode(520) is connected to the data line. A drain electrode(540) faces the source electrode. A semiconductor layer(400) is formed between the source electrode and the drain electrode. A pixel electrode(700) is connected to the drain electrode.
