Abstract

A liquid crystal display includes a plurality of subpixels respectively having switching elements and arranged in a matrix, a plurality of gate lines connected to the subpixels via the switching elements and transmitting a gate signal for turning on or off the switching elements, and a plurality of data lines connected to the subpixels via the switching elements and transmitting a data voltage. The respective subpixels are located in areas defined by two adjacent gate lines and two adjacent data lines, which are uniquely connected to a pair of gate line and data line, and at least one of the subpixels is connected to the different gate lines or the data line positioned at opposite side with respect to the other subpixel of the same row. In this case, a pair of subpixels adjacent above and below are connected to the gate line therebetween or the gate lines positioned at opposite side each other. In this way, any inversions for each color can be performed without changing conventional driving ICs.
