CONSTITUTION:A light emitting diode 7 inside the optical MOS FET relay 9 is turned on/off by an optical MOS FET relay control signal 6 through the limiting resistance 5 of a control power source 16 based on an output signal. By responding to the on/off of the diode 7, a MOS FET 8 functions as a turning on/off switch. Then, the AC power supply for driving the EL, which is generated by controlling the optical MOS FET relay 9, drives to perform the light emission of an EL element 12 which is switched by the MOS FET 8, connected to the EL electrode 10, paired with either a single phase AC power supply EL common electrode line and corresponds to the connection through a line 4. Thus, the optical MOS FET relay 9 is provided in accordance with the number of the EL element 12 of an EL display panel, so that an efficient EL light emitting display panel is realized.
