TFT SUBSTRATE FOR LCD AND FABRICATION METHOD OF THE SAME

摘要

PURPOSE: A TFT substrate for LCD and a fabrication method of the same are provided to remove afterimage by decreasing DC components and simplify fabrication process by decreasing masks. CONSTITUTION: A fabrication method of TFT substrate for LCD comprises steps of: forming gate lines and gate electrodes connected to the gate lines on an insulation substrate; forming a gate insulation film covering the gate lines; forming semiconductor patterns on the gate insulation film; forming a data wiring comprising source and drain electrodes and data lines connected to the source electrodes; depositing a protect film having a first contact hole exposing the drain electrodes and covering the data wiring; and forming pixel electrodes connected to the drain electrodes through the first contact hole.
