THIN FILM TRANSISTOR SUBSTRATE AND METHOD FOR MANUFACTURING THE SAME AND DISPLAY DEVICE USING THE SAME

摘要

PURPOSE: A thin film transistor substrate and a manufacturing method thereof, and a display device using the same are provided to enhance on-current features of a thin film transistor without increasing resistance of a gate electrode. CONSTITUTION: An etch stopper(150) is formed on an active layer. The etch stopper comprises a first contact hole and a second contact hole to expose a predetermined area of the active layer. A source electrode(192) is electrically connected to the active layer through the first contact hole. A drain electrode(194) is electrically connected to the active layer through the second contact hole. A pixel electrode(180) is connected to the drain electrode on a lower surface of the drain electrode.
