Patent ID: 7701541

Claim:
An In-Plane Switching display device comprising: a pair of substrates; at least one thin film transistor formed over one of the pair of substrates; an organic resin film formed over the thin film transistor; an electrode formed on the organic resin film; and a pixel electrode formed on the organic resin film and electrically connected to the thin film transistor via a contact hole in the organic resin film, wherein the thin film transistor comprises a semiconductor island with at least two channel forming regions and an n-type impurity region between the two channel forming regions therein, a gate insulating layer on the semiconductor island, and first and second gate electrodes on the gate insulating layer, wherein the electrode and the pixel electrode are in contact with an upper surface of the organic resin film, wherein the electrode sets a fixed electric potential, and wherein the electrode overlaps the at least two channel forming regions and the n-type impurity region in the semiconductor island.
