1. An electronic apparatus comprising:
an electronic module; and
a flexible substrate electrically connected to the electronic module,
the flexible substrate including:
a base film;
a plurality of first contact pads arranged at one end on the base film in a first direction, and electrically connected to the electronic module;
a plurality of second contact pads arranged at another end on the base film in the first direction;
a plurality of first wires arranged on the base film, and each electrically connecting one of the first contact pads and one of the second contact pads together; and
a plurality of third contact pads arranged on the base film, each of the third contact pads being positioned along the first direction between one of the first contact pads and one of the second contact pads, and being electrically connected to one of the first wires,
the electronic apparatus further comprising a fourth contact pad and a fifth contact pad arranged on the base film, electrically insulated from the first wires, and electrically connected together, wherein:
the fourth contact pad and the fifth contact pad are disposed in different positions along the first direction; and
the fourth contact pad is positioned closer to the one end in the first direction than the third contact pads are, and the fifth contact pad is positioned closer to the other end in the first direction than the third contact pads are,
the electronic apparatus further comprising a sixth contact pad and a seventh contact pad arranged on the base film, electrically insulated from the first wires, and electrically connected together, wherein:
the sixth contact pad is positioned closer to the other end in the first direction than the third contact pads are, and the seventh contact pad is positioned closer to the one end in the first direction than the third contact pads are;
the fourth contact pad and the fifth contact pad are positioned closer to one end in a second direction than the third contact pads are, the second direction being orthogonal to the first direction; and
the sixth contact pad and the seventh contact pad are positioned closer to another end in the second direction than the third contact pads are.
