1. A liquid crystal display device comprising a first pixel and a second pixel,
wherein the liquid crystal display device comprises a first common electrode, a second common electrode, an auxiliary wiring, a light-blocking layer, and a liquid crystal layer,
wherein the first pixel comprises a first transistor and a first pixel electrode,
wherein the second pixel comprises a second transistor and a second pixel electrode,
wherein the first common electrode, the auxiliary wiring, the first transistor, and the second transistor are provided over a first substrate,
wherein, in a cross-sectional view of the liquid crystal display device, the first common electrode is positioned between the first transistor and the liquid crystal layer,
wherein in a top view of the liquid crystal display device, the first common electrode overlaps with the first pixel and the second pixel,
wherein in a top view of the liquid crystal display device, the first common electrode comprises a first opening and a second opening,
wherein in a top view of the liquid crystal display device, the first opening comprises a first region which the first transistor is in contact with the first pixel electrode,
wherein in a top view of the liquid crystal display device, the second opening comprises a second region which the second transistor is in contact with the second pixel electrode,
wherein the first common electrode is in contact with the auxiliary wiring at a third region,
wherein the second common electrode overlaps with the first common electrode, the first pixel electrode, and the second pixel electrode,
wherein the second common electrode includes a third opening,
wherein, in a cross-sectional view of the liquid crystal display device, the third opening overlaps with a region which is not provided with the first pixel electrode, and
wherein the third region overlaps with the light-blocking layer.
