Abstract:
1. A liquid crystal display device comprising: gate lines and data lines crossing each other; a gate driver applying gate scan signals to the gate lines; and a data driver applying pixel data voltages to the data lines, and including a multiplexer which includes first and second switches that allow a power supply terminal and a ground terminal to be alternatively connected, wherein the first switch includes a first gate electrode, a first source electrode and a first drain electrode, and the second switch includes a second gate electrode, a second source electrode and a second drain electrode, wherein the first source electrode is connected to the power supply terminal, and the first drain electrode is connected to an output terminal output which is connected to a buffer portion of the data driver, and the first gate electrode is connected to the second drain electrode and, the second source electrode is connected to the ground terminal, and the second gate electrode receives a control signal from the exterior, wherein the first and second switches configure a formation in which one is selectively turned on by the control signal and then the other one is turned off, wherein the first drain electrode is adjacent arranged the second source electrode, wherein the first drain electrode is separated from the second source electrode at a fixed interval.
