    • A driving device of a display apparatus and a driving method thereof are provided to transmit a data signal without distortion between a signal controller and a source driver accurately. A liquid crystal display device include a liquid crystal panel assembly(300), a gate driver(400), a data driver(500), a gray voltage generator(800) and a signal controller(600). The gray voltage generator generates the whole gradation voltage or a reference gradation voltage relating to the transmittance of a pixel. A signal controller generates a data signal according to an input image signal and generates a clock signal according to the input control signal. The signal controller generates a differential pair image signal by modulating the clock signal in the data signal and converts the data signal section and the clock signal section of the differential pair image signal into other level. The signal controller converts the differential pair image signal of the section in which the level of the data signal is converted during the data signal section, to the same level as the differential pair image signal of the clock signal section for the predetermined initial emphasis period.
