ABSTRACT:
The present invention concerns a liquid crystal display device including: a substrate; a plurality of thin film transistors each including a gate electrode, a source electrode, and a drain electrode; a gate line and a data line electrically connecting with the gate electrode and the source electrode, respectively; and a pixel electrode electrically connecting with the drain electrode, wherein overlapping widths between the gate electrode and the source and drain electrodes vary in accordance with the position of the thin film transistor.
