Claim Text:
1. A liquid crystal display device comprising: a transistor comprising: a first conductive layer on and in electrical contact with the semiconductor layer; a second conductive layer on a same plane and of a same material as the first conductive layer; a first insulating layer over the transistor and over the first and the second conductive layers; a transmitting common electrode overlapping the second conductive layer; a third conductive layer on and in direct contact with the transmitting common electrode, the third conductive layer overlapping the second conductive layer and the first insulating layer; a second insulating layer on and in direct contact with the first insulating layer and with the third conductive layer; and a transmitting pixel electrode on and in direct contact with the second insulating layer, overlapping the transmitting common electrode, and in electrical contact with the first conductive layer via a second contact hole in the second insulating layer and a first contact hole in the first insulating layer, wherein the first contact hole and the second contact hole overlap.
