1. A display device comprising:

  • a substrate;

    a scan line;

    a signal line intersecting with the scan line over the substrate;

    a pixel portion in which pixel electrodes are arranged in matrix; and

    a first non-linear element provided over the substrate in a region outside the pixel portion,wherein the pixel portion comprises a thin film transistor in which a channel formation region is in a first oxide semiconductor layer,wherein the thin film transistor comprises;

    a gate electrode which is connected to the scan line;

    a first wiring layer which is connected to the signal line and the first oxide semiconductor layer; and

    a second wiring layer which is connected to one of the pixel electrodes and the first oxide semiconductor layer,wherein the first non-linear element comprises;

    a gate electrode;

    a second oxide semiconductor layer over the gate electrode of the first non-linear element;

    a channel protective layer covering a region which overlaps with a channel formation region of the second oxide semiconductor layer; and

    a first wiring layer and a second wiring layer being over the channel protective layer and the gate electrode of the first non-linear element,wherein the gate electrode of the first non-linear element is connected to the scan line,wherein one of the first wiring layer and the second wiring layer of the first non-linear element is directly connected to a wiring in the same layer as the gate electrode of the first non-linear element, andwherein at least one of the first oxide semiconductor layer and the second oxide semiconductor layer includes a nanocrystal.
