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.
