1. A display device comprising:

  • a substrate;

    a gate electrode disposed on the substrate;

    a common electrode layer disposed on the substrate;

    a gate insulator disposed on the gate electrode, the gate insulator not overlapping the common electrode layer in a first direction perpendicular to a surface of the substrate;

    a first insulating layer disposed on the common electrode layer, the first insulating layer not overlapping the gate electrode in the first direction;

    a semiconductor disposed on the gate insulator;

    a source electrode and a drain electrode which are disposed on the semiconductor;

    a second insulating layer disposed on the source electrode, the drain electrode and the first insulating layer; and

    a pixel electrode disposed on the second insulating layer and overlapping the common electrode,wherein any semiconductor is not disposed between the first insulating layer and the second insulating layer.
