A liquid crystal display panel includes a first substrate, a second substrate, and a liquid crystal layer formed between the first substrate and the second substrate. A pixel area is formed on the first substrate, and a driver is formed on the substrate and electrically connected with the pixel area. A plurality of lines are electrically connected with the driver, and a plurality of pads are electrically connected with the plurality of lines. The plurality of pads are formed in a straight line and are not electrically connected with each other except for the electric connection with the plurality of lines.

Liquid crystal display device and manufacturing method thereof

A display device includes a substrate, a display area and a peripheral area formed on the substrate, a plurality of signal lines and a plurality of scan lines arranged in the display area, and six signal line common lines provided in said peripheral area. Each signal line common line of the six signal line common lines is connected every six signal lines. At least two scan line common lines are provided in the peripheral area, and each scan line common line of at least two scan line common lines is connected every predetermined of scan lines.

Liquid crystal display device comprising a peripheral area having six signal common lines each connected every six signal lines

A display device having a substrate with a display area and a peripheral area being formed on the substrate. A plurality of signal lines and a plurality of scan lines are arranged in the display area. Six signal line common lines are provided in the peripheral area and at least one of two, three and four scan line common lines are provided in the peripheral area.

Liquid crystal display device comprising a peripheral area having six signal line common lines each connected every six signal lines in a driver IC mount region and four scan line common lines each connected to every four scan lines

Drain driver output terminals (lead lines) are divided into six groups (R , R , G , G , B , B ) of positive polarity and negative polarity for three primary colors: respective ones are bundled together for connection to drain line common lines; and then, these drain line common lines are drawn out of a drain driver mount region. Gate driver output terminals (lead lines) are divided into three groups (GA, GB, GC) including a front stage and a next stage plus a rear stage; and respective ones are bundled together for connection to gate line common lines. These gate line common lines are drawn out of a gate driver mount region; and then, tests are preformed with probes attached to test terminals provided at such drain line common lines and gate line common lines.
