Abstract

Provided is an electroluminescence apparatus comprising a first unit having a simple matrix electrode structure and an electroluminescence member provided at each intersection between a scanning signal line and an information signal line; and a second unit for sequentially applying a scanning selection signal comprising a first phase and a second phase of mutually different voltage waveforms to the scanning signal line, applying a light emission inducing signal to produce a voltage over a threshold for light emission of the electroluminescence member in synchronism with one of the first phase and the second phase, to the information signal line, and applying a light emission non-inducing signal comprised of a voltage different from that of the light emission inducing signal, in synchronism with the other phase to the information signal line, thereby applying an alternating voltage to the electroluminescence member during a non-selection period of scanning.
