A luminescent display device and a method for driving the same are disclosed which are capable of increasing the aspect ratio of pixel regions. The luminescent display device includes a display including gate lines, and data lines extending orthogonally to the gate lines, a first shift register connected to one end of each of the gate lines, to sequentially supply first scan pulses to the gate lines, respectively, a second shift register connected to the other end of each of the gate lines, to sequentially supply second scan pulses to the gate lines, respectively, switching elements each adapted to switch an ON voltage or an OFF voltage from the associated data line in accordance with the first scan pulse from the associated gate line, 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 each adapted to generate current in accordance with the ON voltage from the associated switching element, each drive switching element being turned off in accordance with the OFF voltage from the associated switching element, capacitors each connected between gate and source terminals of an associated one of the drive switching elements, and light emitting elements each adapted to emit light in accordance with the current from the associated drive switching element.
