Claim:
A liquid crystal display device comprising: a liquid crystal panel including a plurality of odd and even numbered data lines arranged along a short-axis direction of substrate, and a plurality of gate lines arranged along a long-axis direction of substrate, wherein each gate line is orthogonal to each data line; a data driving circuit to supply data voltages to the data lines; a gate driving circuit to supply scan pulses to the gate lines; and a timing controller to supply digital video data to the data driving circuit, and to control the data driving circuit and the gate driving circuit, wherein two sub-pixels with one gate line interposed therebetween use one gate line in common; wherein the liquid crystal panel comprises: a plurality of red sub-pixels arranged along the short-axis direction of substrate; a plurality of green sub-pixels arranged along the short-axis direction of substrate; and a plurality of blue sub-pixels arranged along the short-axis direction of substrate; wherein the sub-pixels positioned at the left side of the gate line are supplied with the data voltage from the odd numbered data line, and the sub-pixels positioned at the right side of the gate line are supplied with the data voltage from the even numbered data line, on assumption that the plurality of red, green and blue sub-pixels are provided with the gate line interposed in-between; wherein the gate driving circuit generates the scan pulse whose pulse width corresponds to ½ of one horizontal period; wherein the data driving circuit firstly supplies the red and green data voltages corresponding to the red and green digital video data to the respective odd and even numbered data lines during about ½ horizontal period; secondly supplies the blue and red data voltages corresponding to the blue and red digital video data to the respective odd and even numbered data lines during about horizontal period; and thirdly supplies the green and blue data voltages corresponding to the green and blue digital video data to the respective odd and even numbered data lines during about ½ horizontal period.
