Abstract
A liquid crystal display device and a method for driving the same are disclosed. The device includes a gamma voltage generation circuit for generating first to ith positive gamma reference voltages having different levels, and first to ith negative gamma reference voltages having different levels, and a plurality of data drive chips, each of the data drive chips converting digital data input thereto into a positive data voltage and a negative data voltage and supplying the positive data voltage and negative data voltage to a liquid crystal display panel, and adjusting a level of the positive data voltage based on a positive gamma reference voltage supplied thereto, among the first to ith positive gamma reference voltages, and adjusting a level of the negative data voltage based on a negative gamma reference voltage supplied thereto, among the first to ith negative gamma reference voltages.
