Abstract
Disclosed is a liquid crystal display device that includes a TFT substrate. A plurality of gate lines and a plurality of common lines extend in a first direction on the TFT substrate. Drain lines extend in a second direction substantially perpendicularly to these lines. Bus lines are located outside a display area and are extending parallel to the drain lines. Common line terminals are provided on either side of each block that is constituted by a predetermined number of gate terminals. The common line terminals and the lead lines therefor are formed on the same layer as the drain lines and are connected to the bus lines on the same layer without any contacts being used. Resistance along the routes taken by common lines can be reduced.
