摘要 |
Charge corresponding to a potential difference between electrodes of an electroluminescence element is accumulated in a period in which the electroluminescence element emits light; the potential difference is detected without decrease in the luminance at the time of light emission of the electroluminescence element; and a reference potential of one electrode of the electroluminescence element is changed based on the detected potential difference, so that reduction in luminance of the electroluminescence element due to deterioration of the electroluminescence element is compensated.
