A liquid crystal display is disclosed. The liquid crystal display includes a liquid crystal display panel including data lines and gate lines crossing one another and a pixel array including liquid crystal cells arranged in a matrix format according to a crossing structure of the data lines and the gate lines, a source drive circuit supplying a data voltage to the data lines through a plurality of output channels, a gate drive circuit sequentially supplying a gate pulse to the gate lines. The liquid crystal display panel includes link lines that respectively connect the data lines to the output channels of the source drive circuit. The source drive circuit includes a plurality of output channel resistors connected between the output channels and the link lines. Each of the output channel resistors includes a variable resistance circuit.

A liquid crystal display and a method of driving the same are provided. The liquid crystal display includes a liquid crystal display panel including data lines, gate lines crossing the data lines, and liquid crystal cells and having a quad type pixel structure in which red, green, blue, and white subpixels constitute one pixel, a logic circuit sequentially outputting polarity control signals, a data drive circuit that inverts a polarity of a data voltage in response to the polarity control signals to supply the data voltage with the inverted polarity to the data lines, and a gate drive circuit sequentially supplying gate pulses to the gate lines. A logic level of each of the polarity control signals is inverted every three horizontal periods, and phases of the polarity control signals are different from one another.
