Abstract:
1. A liquid crystal display device, comprising: a gate line having a double layered structure including a transparent first conductive layer and an opaque second conductive layer on the transparent first conductive layer; a data line crossing the gate line to define a pixel area; a thin film transistor connected to the gate line and the data line; a common line having first and second conductive layers and substantially parallel to the gate line, wherein the common line is formed in the same layers as the gate line; a common electrode extended from the first conductive layer as a lower layer of the common line in the pixel area, wherein the common electrode is formed of the first conductive layer as the same layer as the first conductive layer of the common line; and a pixel electrode connected to the thin film transistor to form a horizontal electric field with the common electrode in the pixel area, wherein a width of the lower first conductive layer in each of the gate line and the common line is wider than a width of the upper second conductive layer, and wherein the gate line, the common line and the common electrode are formed on the same layer.
