Patent ID: 7304710

Claim:
A liquid crystal display device comprising a first substrate, a second substrate, a liquid crystal layer between the first substrate and the second substrate, wherein the first substrate has a pixel area, a peripheral area, gate lines, drain lines, first gate connecting lines, second gate connecting lines, a first insulating film, and a second insulating film, the pixel area includes pixel electrodes, the gate lines and the drain lines, the peripheral area surrounds the pixel area, the gate lines include first gate lines and second gate lines, first gate connecting lines and second gate connecting lines are disposed in the peripheral area, the respective first gate connecting lines electrically connect the first gate lines to a liquid crystal driving circuit, the respective second gate connecting lines electrically connect the second gate lines to the liquid crystal driving circuit, the first insulating film insulates the first gate connecting lines from the second gate connecting lines, the first gate connecting lines and the second gate connecting lines are stacked in a thickness direction of the first substrate, the second insulating film is formed as a higher layer than the first gate connecting lines and the second gate connecting lines within the first substrate, and the second insulating film expands from the peripheral area to the pixel area.
