Abstract

Disclosed herein is a liquid crystal display device which is capable of reducing the number of data drive integrated circuits (ICs) to curtail a production cost. The liquid crystal display device includes a plurality of pixel cells formed respectively in areas defined by a plurality of gate lines and a plurality of data lines, a first unit pixel including at least three of the pixel cells, the at least three pixel cells being connected to different ones of the data lines, and a second unit pixel including at least three of the pixel cells other than the at least three pixel cells of the first unit pixel, the at least three pixel cells of the second unit pixel being connected respectively to the different data lines to which the at least three pixel cells of the first unit pixel are connected, wherein the first and second unit pixels are arranged in a direction of the data lines and connected to different ones of the gate lines. A plurality of adjacent pixel cells expressing the same colors or different colors on horizontal lines, among the pixel cells, are connected in common to the same data lines.

Claims (9)

1. A liquid crystal display device comprising:

a gate driver for sequentially supplying a drive signal to a plurality of gate lines;

a data driver for supplying video data signals respectively to a plurality of data lines; and

a plurality of pixel cells formed respectively in areas defined by the gate lines and the data lines,

wherein a plurality of adjacent pixel cells are connected in common to the same data lines, wherein the plurality of adjacent pixels connected in common to the same data lines are expressing the same colors or different colors on the horizontal lines, among the pixel cells.

2. The liquid crystal display device according to claim 1 , wherein the data lines to which the adjacent pixel cells expressing the same colors on the horizontal lines are connected in common are branched off from channels connected to the data driver.

3. The liquid crystal display device according to claim 1 , wherein the data lines to which the adjacent pixel cells expressing the different colors on the horizontal lines are connected in common are branched off from channels connected to the data driver.

4. The liquid crystal display device according to claim 2 or 3 , wherein the channels are the same in number as the data lines to which the adjacent pixel cells expressing the same colors on the horizontal lines are connected in common.

5. The liquid crystal display device according to claim 2 or 3 , wherein the channels are the same in number as the data lines to which the adjacent pixel cells expressing the different colors on the horizontal lines are connected in common.
