PURPOSE:To make drividing by AC power possible and increase durability of light emission performance by a method wherein two kinds of electrode elements are laminated in a light transmitting electrode, a work function of an electrically conductive substance contained in each electrode element is different, and the electrode elements are arranged periodically so as to face each other via an organic compound layer in a pair of facing electrodes. CONSTITUTION:An electroluminescent device comrises an electrode element 5 formed of light transmitting base 1,2, light transmitting electrodes 3, 4, and a first conductive substance, an electrode element 6 formed of a second conductive substance having a work function different from that of the first conductive substance, an organic compound layer 7, and a power supply 8. Any shape can be taken for the electrode element 5, for example, stripe or mosaic shape, if they can be arranged in a periodic manner. The electrode elements 6 should preferably be arranged in such a way that they are alternately arranged periodically together with the electrode elements 5 on each interface with the organic compound layer 7, and that they are arranged facing the electrode elements 5 with the organic compound layer 7 provided therebetween. |
