1. A luminescent display device that comprises:

  • a display that includes a plurality of gate lines and a plurality of data lines that extend orthogonally to the gate lines;

    a first shift register connected to one end of each of the gate lines, and adapted to sequentially supply first scan pulses to the gate lines;

    a second shift register connected to the other end of each of the gate lines, and adapted to sequentially supply second scan pulses to the gate lines;

    switching elements adapted to switch an ON voltage or an OFF voltage from one of the data lines in accordance with the first scan pulse from one of the gate lines, and to switch an OFF voltage from the associated data line in accordance with the second scan pulse from the associated gate line;

    drive switching elements adapted to generate current in accordance with the ON voltage from an associated one of the switching elements, wherein the drive switching elements are turned off in accordance with the OFF voltage from the associated switching element;

    capacitors connected between gate and source terminals of one of the drive switching elements; and

    light emitting elements adapted to emit light in accordance with the current from an associated one of the drive switching elements.
