Patent attributes
A horizontal electric field applying type thin film transistor substrate of a LCD device having an increased aperture ratio as well as a simplified manufacturing process. The device includes a gate line having a double layered structure including a transparent first conductive layer and an opaque second 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; a common electrode extended from the first conductive layer of the common line in the pixel area; and a pixel electrode connected to the thin film transistor to form a horizontal electric field with the common electrode in the pixel area.
