THIN FILM TRANSISTOR ARRAY PANEL AND METHOD FOR MANUFACTURING THE SAME

摘要

PURPOSE: A thin film transistor array panel and a method for manufacturing the same are provided to reduce the signal delay while not forming a gate wiring and gate insulating layer thickly by forming a secondary insulating layer. CONSTITUTION: A gate line has a gate electrode while locating on the insulating substrate. A secondary insulating layer(30) locates on the gate line. A gate insulating layer(140) is located on the supplementary insulating layer and an insulating substrate. A semiconductor(154) is locates on the gate insulating layer. The data line has the source electrode piled up one with the above semiconductor. A drain electrode(175) puts opposite to the source electrode while being piled up one with the semiconductor. A protective film locates on the data line and the drain electrode. The pixel electrode is connected to the drain electrode.
