A liquid crystal display includes a liquid crystal display panel on which gate lines and data lines cross one another and liquid crystal cells are respectively arranged at crossings of the gate lines and the data lines in a matrix form, a panel common line connected to common electrodes of the liquid crystal cells, a power supply circuit generating a common voltage to be applied to the common electrodes, data circuit groups each including a data driver integrated circuit (IC) for driving the data lines, and gate circuit groups each including a gate driver IC for driving the gate lines. The gate circuit groups is connected to one of the plurality of data circuit groups through a first line-on-glass (LOG) type signal line group.
