| 1. A liquid crystal display device, comprising:
a double-layer structure of a gate line, the double layer having a first transparent conductive layer and a second opaque
conductive layer and having a step coverage;
a data line crossing to the gate line to define a pixel region;
a gate insulating film between the gate line and the data line;
a thin film transistor connected to the gate line and the data line;
a semiconductor layer defining a channel of the thin film transistor and overlapping with the data line;
a passivation film covering the data line and the thin film transistor;
a pixel electrode directly formed on the gate insulating film which is exposed by a pixel hole in the pixel region; and
a storage capacitor overlapping with the pixel electrode having the gate insulating film therebetween and having a lower storage
electrode extended from the first transparent conductive layer.
