Display device

A display device comprising:

• a first substrate;
• a second substrate;
• and
• a liquid crystal layer disposed between the first substrate and the second substrate, the first substrate comprising:
• a plurality of pixels arranged in a display portion, each of the pixels including a pixel electrode;
• a plurality of thin film transistors, each electrically connected to a corresponding one of the pixel electrodes;
• a plurality of signal lines electrically connected to the thin film transistors;
• a common electrode opposed to the pixel electrodes, the liquid crystal layer being controlled by an electric field between the pixel electrodes and the common electrode;
• a first insulating film interposed between the pixel electrodes and the common electrode;
• a second insulating film disposed under the common electrode and the pixel electrodes;
• a first common line being disposed along at least one side of the display portion and intersecting the signal lines, in plan view;
• a plurality of contact holes each electrically coupling the first common line and the common electrode;
• a plurality of gate lines electrically connected to the thin film transistors;
• a second common line being disposed along at least another side of the display portion and intersecting the gate lines, in plan view, a plurality of contact holes each electrically coupling the second common line and the common electrode;
• and
• a bridge that is disposed at an intersection of the first common line and one of the signal lines, the bridge being formed in a same layer as the gate lines, wherein the common electrode overlaps the entire area of the display portion,
• wherein
• the contact holes are arranged in a first direction along the first common line in such a manner that a distance between the contact holes in the first direction is less than a length of each pixel in the first direction, and
• the contact holes are arranged in a second direction along the second common line in such a manner that a distance between the contact holes in the second direction is less than a length of each pixel in the second direction.
