Patent ID: 8575619

Claim:
An LCD display device comprising: a transistor comprising a gate wiring and two channel forming regions, the transistor being formed in a pixel region; a first insulating layer over the transistor; a first wiring, a second wiring, and a third wiring each formed over the first insulating layer; a second insulating layer over the first wiring, the second wiring, and the third wiring, the second insulating layer comprising a contact hole; an electrically conductive film over the second insulating layer, the electrically conductive film comprising an opening, the contact hole of the second insulating layer overlapping with the opening; a third insulating layer over the electrically conductive film and the second insulating layer; a pixel electrode over the third insulating layer, the pixel electrode comprising a first region overlapping with the electrically conductive film and a second region not overlapping with the electrically conductive film, wherein the pixel electrode is electrically connected to the first wiring through the contact hole, wherein the first wiring is electrically connected to a drain region of the transistor, wherein the third wiring is electrically connected to a source region of the transistor, wherein the gate wiring comprises a region overlapping with the opening and one of the two channel forming regions, wherein the first wiring comprises a region overlapping with the opening and the one of the two channel forming regions, wherein the third wiring comprises a region overlapping with the other one of the two channel formation regions, and wherein the second wiring is electrically connected to the electrically conductive film in a region outside of the pixel region.
