Abstract
A thin film transistor substrate of a LCD device and a fabricating method thereof are disclosed for simplifying a fabricating process and enlarging a capacitance value of a storage capacitor without any reduction of aperture ratio. The LCD device includes: a double-layered gate line having a first transparent conductive layer and a second opaque conductive layer, the second opaque conductive layer have a step coverage; a gate insulation layer film on the gate line; a data line crossing the gate line to define a pixel region; a TFT connected to the gate line and the data line; a pixel electrode connected to the TFT via a contact hole of a protective film on the TFT; and a storage capacitor overlapping the pixel electrode and having a lower storage electrode formed of the first transparent conductive layer.
