THIN FILM TRANSISTOR SUBSTRATE, FLAT PANEL DISPLAY INCLUDING THE SAME, AND METHOD OF MANUFACTURING THE THIN FILM TRANSISTOR SUBSTRATE

摘要

PURPOSE: A substrate having a capacitor and a TFT(Thin Film Transistor), a flat display device equipping the same and a manufacturing method of the same with the capacitor and the TFT are provided to reduce manufacturing cost and simplify a manufacturing process. CONSTITUTION: A first capacitor electrode has conductive property to be formed into a doped semiconductor layer doped with the semiconductor layer arranged in the same layer. An insulating layer(116) covers the above semiconductor layer and the first capacitor electrode. A gate electrode corresponding to the partial domain of the semiconductor layer and a second capacitor electrode corresponding to the first capacitor electrode are arranged on the insulating layer. The thickness of the gate electrode is thicker than the thickness of the second capacitor electrode.
