Disclosed is a liquid crystal display device in which printed circuit board (PCB) modules are suitably arranged to form a large screen with high resolution. The liquid crystal display device includes first and second main PCBs for driving a dual bank type liquid crystal panel, the first main PCB having a timing controller for processing external odd input signals to generate driving signals, and sending part of the driving signals to a corresponding source driver PCB, so as to generate video signals to be supplied to the odd pixels of the liquid crystal panel; and the second main PCB having a timing controller for processing external even input signals to generate driving signals, and sending part of the driving signals to a corresponding source driver PCB, so as to generate video signals to be supplied to the even pixels of the liquid crystal panel. According to the present invention, two source driver PCBs are used to supply video data to the upper part and the lower part of the liquid crystal panel, respectively, and thereby to reduce signal delay and distortion in driving the dual bank type liquid crystal display device for a large screen with high resolution, thus solving the problems of coupling between signals more deviating from the tolerance range with an increased frequency, noise, and EMI.
