Abstract:
1. A liquid crystal display device, comprising: a liquid crystal display panel; a pixel region and a driving circuit region; a driving circuit on a liquid crystal display panel supplying a driving signal to the liquid crystal display panel; and a switching device located in the driving circuit region and including a plurality of thin film transistor groups connected substantially in parallel with a gate line, a source line and a drain line, wherein each thin film transistor group includes a plurality of thin film transistors connected substantially in parallel with a gate electrode branched from the gate line, a source electrode branched from the source line, and a drain electrode branched from the drain line, wherein the plurality of thin film transistors include a single semiconductor pattern overlapping the gate electrode, the semiconductor pattern non-overlapping the gate line, the source line and the drain line, and being independently formed in the each thin film transistor group,
