ABSTRACT:
This invention relates to a liquid crystal display device that bias-aging is possible even after spreading silicon over an on/off pad.A liquid crystal display device according to an embodiment of the present invention includes a liquid crystal display panel where liquid crystal cells are arranged in an active matrix pattern between an upper substrate and a lower substrate, and where a plurality of gate lines and a plurality of data lines are formed; an on/off pad formed on the lower substrate for supplying bias aging signals to the gate line and the data line and checking whether or not the liquid crystal cells are turned on; a drive IC formed on the lower substrate for supplying drive signals to the gate line and the data line; and a printed circuit board which is connected to the lower substrate and which has a signal pad for supplying the drive signal to the drive IC and a bias aging pad for supplying the bias aging signal to the on/off pad.
