Abstract
An organic electroluminescence device, which includes a transparent conductive layer, a light emitting unit layer, transparent insulator dielectric layer and an electrode layer which are stacked up layer by layer sequentially. The light emitting unit layer includes a first light emitting unit and a second light emitting unit which are arranged in juxtaposition and with an interval; through arranging the first light emitting unit and the second light emitting unit in juxtaposition and with an interval, making the organic electroluminescence device can be directly connected to external alternating current, not only can dispense from the energy dissipation causing by converting alternating current to direct current, but also can improve the luminous efficacy of the device; and makes the whole organic electroluminescence device be thin and light.
