Abstract

PURPOSE: A three-layer formation film EL element which has hysteresis phenomenon in the applied voltage characteristic of light emitting luminance is caused to emit light with an AC maintained pulse train. Then, light is irradiated with a light pen to erase the emitting of light. The mode of pulse application waveform of this time is to be improved.
