Abstract: Disclosed is a liquid crystal display device including a liquid crystal panel having a shift register therein and an interface circuit for adjusting DC and AC levels, for compensating for a loss caused by elements and a resister of the shift register. A driving circuit of the liquid crystal display device includes a clock generation unit outputting a first clock signal as a gate clock signal, a second clock signal as an inverse signal of the first clock signal, and a start pulse, and a DC and AC level amplification unit for amplifying the first and second clock signals and the start pulse after adjusting DC and AC levels of the first and second clock signals and the start pulse, and outputting the first and second clock signals and the start pulse to the shift register.
