ABSTRACT:
A liquid crystal display device free of breakdown caused by static electricity substrate. The liquid crystal display device includes pixels regularly arranged on the transparent insulating substrate, data bus lines arranged among the pixels on the transparent insulating substrate and adapted to send video data to the pixels, a high level voltage source, a low level voltage source, a gate driving circuit adapted to receive required voltages from the voltage sources and generate gate driving signals, gate bus lines arranged among the pixels such that the gate bus lines cross the data bus lines and adapted to transmit the gate driving signals, a gate insulating film formed on the transparent insulating substrate and adapted to insulate the gate bus lines from the data bus lines, thin film transistors respectively connected to the pixels, the gate bus lines and the data bus lines adapted to apply the video data via the data bus lines to the pixels by switching operations thereof based on the gate driving signals, a single short circuit line connected to the data bus lines, and static electricity removing circuits connected between the gate driving circuit and respective of the gate bus lines and electrically connected in common to the high level voltage source, the low level voltage source and the short circuit line.
