摘要：PURPOSE: An LCD device and a TFT(Thin Film Transistor) substrate used for the same are provided to simplify a manufacturing process by installing an aperture pattern and a projection to a pixel electrode. CONSTITUTION: A gate wiring and a sustain electrode wiring formed with an aluminium or an aluminium alloy are arranged on an insulating substrate. The gate wiring is composed of a gate line(22) and a gate electrode(26) of a thin film transistor. The sustain electrode wiring is composed of an upper and a lower sustain electrode line(95,96) and a multitude of sustain electrode(97) connected with the upper sustain electrode line(95) and the lower sustain electrode line(96). The sustain electrodes(97) are splayed. A gate insulating layer is formed on the gate wiring and the sustain electrode wiring. A data wiring and a semiconductor layer(40) are formed on the gate insulating layer. The data wiring comprises a data line(62), a source electrode(65), and a drain electrode(66). A contact layer is formed at a lower portion of the source electrode(65) and the drain electrode(66). A protective layer having a contact hole(81) is formed on the data wiring. A pixel electrode(70) having an aperture portion(71) is formed on the protective layer(80). The aperture(71) is overlapped with the sustain electrode(97).
