Claim:
1. A display device having a display panel in which a plurality of gate lines and a plurality of data lines cross each other to define a plurality of pixels, the display panel comprising: a timing control unit that outputs a first data control signal and an image data; a first data driving unit on a first side of the display panel that generates a first data signal from the image data according to the first data control signal, outputs the first data signal to one of the plurality of data lines from the first side, and generates a second data control signal from the first data control signal; and a second data driving unit on a second side of the display panel that generates a second data signal from the first data signal according to the second data control signal, the second data signal substantially synchronized with the first data signal, and outputs the second data signal to the one of the plurality of data lines from the second side, wherein the second data driving unit comprises: a reference voltage generating unit that generates a first reference voltage and a second reference voltage having different levels from the first data signal; and a switching unit that outputs one of the first reference voltage and the second reference voltage as the second data signal according to the second data control signal.
