An LCD is provided to divide a source PCB and integrate a control PCB into a system board, thereby reducing the size of the system board and the number of output pins and accordingly reducing a manufacturing cost. An LCD(Liquid Crystal Display) panel(30) includes first and second data line groups. In the LCD panel, plural LC cells are disposed in a matrix. A timing controller(31) and a graphic processing circuit(36) are mounted in a system board(40). The timing controller outputs a timing control signal and data, for controlling the first and second data line groups, through a single output port(63). The graphic processing circuit converts image data, inputted from the outside, according to a resolution of the LCD panel and performs signal interpolation and image processing. A first data circuit group includes first data ICs(Integrated Circuits)(32a) for generating data voltage which will be supplied to the first data line group. A first source PCB(Printed Circuit Board)(41A) is connected to the first data circuit group. A second data circuit group includes second data ICs(32b) for generating data voltage which will be supplied to the second data line group. A second source PCB(41B) is connected to the second data circuit group. A connection unit is for electrically connecting the system board to the first and second source PCBs. |
