1. A driving apparatus for a liquid crystal display including a plurality of data lines with sub-pixels arranged at the left and right sides of the data lines connected to each data line, the apparatus comprising:
a liquid crystal display panel having a first and a second liquid crystal cells provided at crossings of a plurality of gate lines and a plurality of data lines, a first switching part driving the first liquid crystal cell, and a second switching part driving the second liquid crystal cell, wherein the first liquid crystal cell and the first switching part are provided at one side of the data lines, wherein the second liquid crystal cell and the second switching part are provided at another side of the data line;
a timing controller that receives red sub-pixel data, green sub-pixel data and blue sub-pixel data and then divides the received data into odd-numbered sub-pixel data and even-numbered sub-pixel data;
a data driver that receives the odd-numbered sub-pixel data and the even-numbered sub-pixel data from the timing controller during one horizontal period and then applies the received odd-numbered and even-numbered sub-pixel data to the data lines during the one horizontal period; and
a gate driver sequentially applying a first and second gate signals to the gate lines so that the second gate signal applied to a ith (wherein i is an integer) gate line overlaps with a part of the first gate signal applied to a (i+2)th gate line,
wherein the first switching part drives the first liquid crystal cell in response to the second gate signal applied to the ith gate line and the first gate signal applied to the (i+2)th gate line,
wherein the second switching part drives the second liquid crystal cell in response to the the second gate signal applied to the ith gate line.
