Patent ID: 7511793

Claim:
A liquid crystal display comprising: a first insulating substrate; a plurality of data lines formed on the first insulating substrate and extending in a substantially column direction; a plurality of gate lines formed on the first insulating substrate and intersecting the data lines; a plurality of additional signal lines formed on the first insulating substrate, parallel to one of the data line and the gate line, and intersecting one of the data line and the gate line; a second insulating substrate disposed opposite the first insulating substrate; a black matrix formed between the first substrate and the second substrate and screening regions defined by the plurality of additional signal lines; a plurality of pixel electrodes and a common electrode to control liquid crystal molecules; a plurality of switching elements transmitting data signals from the plurality of data lines to the pixel electrodes in response to gate signals from the plurality of gate lines; and a controller controlling the liquid crystal display, the controller supplying signals to a data driving circuit and a gate driving circuit, and the controller is electrically connected to the additional signal lines.
