1. A data processing circuit characterized by comprising:

  • first level-conversion means for level-converting a data signal having a first voltage amplitude input in series to a data signal having a second voltage amplitude larger than the first voltage amplitude;

    serial-parallel conversion means for converting the data signal level-converted by the first level-conversion means to parallel data signals; and

    second level-conversion means for level-converting the parallel data signals to data signals having a third voltage amplitude smaller than the second voltage amplitude, and characterized in that the data processing circuit is formed on an insulating substrate by using thin-film transistors.
