Liquid crystal display

A liquid crystal display comprises: a first data drive circuit that supplies a data voltage to data lines present in a first portion and a third portion on the screen of a liquid crystal display panel in response to a first source output enable signal; and a second data drive circuit that supplies the data voltage to data lines present in a second portion and a fourth portion on the screen of the liquid crystal display panel in response to a second source output enable signal. The first source output enable signal controls the data voltage output timing and charge sharing timing of the first data drive circuit. The second source output signal controls the data output timing and charge sharing timing of the second data drive circuit in a different way from the first data drive circuit.
