1. An input/output device comprising:

  • a display portion comprising;

    a signal line; and

    a pixel electrically connected to the signal line, the pixel comprising;

    a first display element;

    a first conductive film electrically connected to the first display element;

    a second conductive film;

    a first insulating film between the first conductive film and the second conductive film;

    a pixel circuit electrically connected to each of the signal line and the second conductive film, the pixel circuit comprising a first transistor and a second transistor;

    a second insulating film comprising a first surface and a second surface which face each other; and

    a second display element electrically connected to the pixel circuit; and

    an input portion configured to sense an object approaching a region overlapping with the display portion, the input portion comprising a sensing element,wherein the sensing element comprises a control line and the signal line,wherein the signal line is positioned so that an electric field which is partly blocked by the object is formed between the signal line and the control line,wherein the first conductive film and the second conductive film overlap each other,wherein the first insulating film comprises a first opening,wherein the second conductive film is electrically connected to the first conductive film through the first opening,wherein the first transistor and the second transistor overlap each other,wherein the first transistor comprises a first semiconductor film,wherein the second transistor comprises a second semiconductor film,wherein the first surface is in contact with the first semiconductor film,wherein the second surface is in contact with the second semiconductor film, andwherein the display portion and the input portion overlap each other.
