Patent ID: 7453540

Claim:
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.
