Abstract:
1. A liquid crystal display device comprising: a first wiring; a transistor comprising: a first insulating layer over the transistor and the first wiring; a second wiring on the first insulating layer, in direct contact with the semiconductor layer through a first opening in the first insulating layer; a third wiring on the first insulating layer, in direct contact with the first wiring through a second opening in the first insulating layer, the third wiring having a same composition and structure as the second wiring; a second insulating layer over the first insulating layer, the second wiring, and the third wiring; a common electrode on the second insulating layer, in electrical contact with the first wiring through the third wiring; an island-shaped conductive layer having a same composition and structure as a portion of the common electrode; a third insulating layer over the second insulating layer, the common electrode, and the island-shaped conductive layer; a pixel electrode on the third insulating layer, overlapping the common electrode and in electrical contact with the semiconductor layer through the second wiring and the island-shaped conductive layer.
