Abstract:
1. A liquid crystal display comprising: a liquid crystal display panel including a display area where a plurality of first pixel units each including at least one liquid crystal cell and a plurality of second pixel units each including at least one liquid crystal cell are positioned and a plurality of data lines and a plurality of gate lines are formed to cross each other; a common voltage generation unit that swings a first common voltage and a second common voltage between two voltage levels in opposite directions every predetermined period of time; a plurality of first longitudinal common lines that are formed parallel to the data lines to supply the first common voltage input through a plurality of first input units to a plurality of first pixel common line patterns formed in the plurality of first pixel units, each of the first pixel common line patterns having mesh structure; a plurality of second longitudinal common lines that are formed parallel to the data lines to supply the second common voltage input through a plurality of second input units to a plurality of second pixel common line patterns formed in the plurality of second pixel units, each of the second pixel common line patterns having mesh structure; and a plurality of data drive integrated circuits (ICs) for driving the data lines, wherein the first input units include a plurality of first common voltage input pads, each of which is connected to one dummy channel of both dummy channels of each of the data drive ICs, and wherein the second input units include a plurality of second common voltage input pads, each of which is connected to the other dummy channel of each of the data drive ICs.
