Abstract:
1. A liquid crystal display device comprising: a gate electrode, a gate line and a dummy pattern formed on a substrate; a first insulation film formed on the gate electrode, the dummy pattern and the gate line, wherein the first insulation film comprises a glass powder; a switching element formed on a portion of the gate electrode and comprising a source electrode, a drain electrode and an active layer; a data line formed over the substrate that intersects the gate line; an amorphous silicon thin film pattern formed at the lower portion of the data line, wherein the dummy pattern is formed adjacent to at least one side of the data line and wherein some portions of the amorphous silicon thin film pattern are formed on the first insulation film and other portions of the amorphous silicon thin film pattern are directly formed on the substrate; a second insulation film formed over the substrate having the source electrode, the drain electrode, the active layer and the data line; a first contact hole exposing a portion of the drain electrode through the second insulation film; and a pixel electrode formed on the substrate and electrically connected with the drain electrode through the first contact hole.
