Transistor Substrate For Flat Panel Display Device and Method For Manufacturing The Same

摘要

PURPOSE: A thin film transistor substrate for a flat panel display device and a manufacturing method thereof are provided to prevent damage to source-drain metal due to etchant and developer by covering a flattering film on an exposed source-drain metal layer. CONSTITUTION: A substrate(SUB) is divided into a display area and a non-display area. A semiconductor layer is formed within the display area on the substrate. A gate insulating layer(GI) covers the semiconductor layer. A first concatenated wire(SL1) is formed on the gate insulating layer. An insulating layer(IN) covers a gate element. A flattering film(PL) covers a source-drain element formed on the display area and the non-display area. An anode electrode is connected to the source-drain element and is formed on the flattering film.
