1. A liquid crystal display device comprising:

  • a transistor comprising;

    a gate electrode;

    a semiconductor layer overlapping with the gate electrode; and

    a gate insulating layer between the gate electrode and the semiconductor layer;

    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.
