Abstract
A liquid crystal display device having first and second substrates; a gate line on the first substrate; a data line crossing the gate line to define a pixel area, the gate line and the data line having a gate insulating film there between; a thin film transistor including a gate electrode, a source electrode, a drain electrode and a semiconductor layer for defining a channel between the source electrode and the drain electrode; a common line in parallel to the gate line on the first substrate; a common electrode extended from the common line in the pixel area; and a pixel electrode spaced apart from the common line and the common electrode in the pixel area to be defined in a pixel hole passing through the gate insulating film, wherein the semiconductor layer overlaps with a source and drain metal pattern including the data line, the source electrode and the drain electrode, and wherein the drain electrode protrudes from the semiconductor layer toward an upper portion of the pixel electrode to be connected to the pixel electrode.
