In a liquid crystal display device having a feedback circuit part, the feedback circuit part prevents black points and blinking pixels from being generated on a liquid crystal display panel by compensating ripple voltages generated from a common electrode of a common substrate. The feedback circuit part comprises a negative feedback part, a buffer part, a low-pass filter part, and first and second impedances interconnecting the low-pass filter part and the negative feedback part.
