Abstract
A liquid crystal display device includes a controller arranged on a data printed circuit board for receiving externally generated video data and clock signals and a resistor for removing electromagnetic noise generated at the controller. Electromagnetic noise such as ESD, interference from other signals, etc., which might be transmitted to a gate driver IC through a resistor formed on a data printed circuit board can be eliminated using a ground voltage and picture quality can be thereby be improved.
