Abstract

A liquid crystal display device is disclosed which includes first, second and third data lines arranged in one direction, a data driver for alternately supplying a data signal of a first polarity and a data signal of a second polarity to each of the first, second and third data lines during an interval of two horizontal periods, first and second gate lines arranged to cross the first to third data lines, a gate driver for sequentially driving the first and second gate lines, and first red, first green, first blue, second red, second green and second blue pixels located between the first gate line and the second gate line and arranged in order along the first and second gate lines. The first red pixel cell is connected to one side of the first data line and the second gate line. The first green pixel cell is connected to the other side of the first data line and the first gate line. The first blue pixel cell is connected to one side of the second data line and the first gate line. The second red pixel cell is connected to the other side of the second data line and the second gate line. The second green pixel cell is connected to one side of the third data line and the first gate line. The second blue pixel cell is connected to the other side of the third data line and the second gate line.

Description

[0001] This application claims the rights and interests of Korean Patent Application No. 10-2006-0095724 filed on September 29, 2006, and the entire contents of which are incorporated herein by reference. Technical field [0002] The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device that can reduce the brightness difference between pixels to improve image quality. Background technique [0003] Generally, a liquid crystal display (LCD) device is suitable for displaying images by adjusting the light transmittance of a liquid crystal cell according to a video signal. The active matrix type LCD device has an advantage in displaying moving images because a switching element is formed therein for each liquid crystal cell. Thin film transistors (TFT) are mainly used as switching elements. [0004] In order to reduce the number of data lines in LCD devices, more attention has recently been paid to data line sharing (DLS...
