Kind Code:
B2
Abstract:
A highly reliable light-emitting device is provided. A lighting device or a display device with a high level of safety and without an exposed electrode is provided. A lighting device or a display device with high layout flexibility is provided. A light-emitting system or a display system to which the light-emitting device or the display device can be applied is provided. An electrode for receiving power and a rectifier circuit are provided in a light-emitting device including an organic EL element and arranged so as to face an electrode for transmitting power, whereby alternating-current power is supplied to the light-emitting device. The alternating-current power is rectified by the rectifier circuit to direct-current power so that the organic EL element in the light-emitting device is driven.
