1. A data driver for providing data voltages to a display panel, the data driver comprising:
a digital-to-analog converting block converting line data into the data voltages;
an option storing block storing a pixel arrangement option representing a pixel arrangement structure of the display panel;
a data swap block connected to the digital-to-analog converting block and the option storing block, and selectively performing a data swap operation that swaps the data voltages based on the pixel arrangement option and whether the line data are odd line data or even line data; and
an output buffer block connected to the data swap block and outputting the data voltages on which the data swap operation is selectively performed to data lines,
wherein the data swap operation is exclusively performed on odd numbered pixel rows or even numbered pixel rows.
