| 1. A display device comprising:
an insulated substrate;
a thin film transistor formed over the insulated substrate;
a first electrode formed over the insulated substrate and connected to one terminal of the thin film transistor;
a second electrode formed over the insulated substrate and formed of a same material as a material of the first electrode;
a first insulating layer formed over the insulated substrate, the first electrode, and the second electrode;
a third electrode formed over the first insulating layer and connected to another terminal of the thin film transistor;
a fourth electrode formed over the first insulating layer, and formed of a same material as a material of the third electrode;
a second insulating layer formed over the first insulating layer, the third electrode, and the fourth electrode;
a fifth electrode formed over the second insulating layer; and a contact hole formed in the first insulating layer and the second insulating layer;
wherein the fifth electrode is connected to the second electrode via the fourth electrode in the contact hole.
