1. A semiconductor device comprising:

  • a first pixel comprising;

    a first common electrode over an insulating surface;

    a gate electrode over the insulating surface;

    a common wiring in contact with a top surface of the first common electrode;

    a gate insulating layer over the first common electrode, the gate electrode, and the common wiring;

    a semiconductor layer over the gate insulating layer;

    an insulating layer over the gate insulating layer and the semiconductor layer;

    a pixel electrode over the insulating layer; and

    a connection electrode over the insulating layer; and

    a second pixel adjacent to the first pixel,wherein the first common electrode comprises a region overlapping with the connection electrode and a region not overlapping with the connection electrode,wherein the first common electrode is electrically connected to a second common electrode of the second pixel though the connection electrode,wherein the first common electrode and the second common electrode are formed by processing a first transparent conductive layer,wherein the gate electrode and the common wiring are formed by processing a second light-shielding conductive layer, andwherein the pixel electrode and the connection electrode are formed by processing a third transparent conductive layer.
