An organic electroluminescent device includes a substrate, a first electrode formed on the substrate, a light emitting layer formed on the first electrode, and a second electrode formed on the light emitting layer. A first electrode lead region is arranged on the first electrode; A second electrode lead region is arranged on the second electrode; An insulated drain wire is provided on the conductive region of the first electrode to increase the conductive separation distance so that the charge is electrically conductive from the first electrode lead region to the second electrode lead region sequentially through the drain wire terminals, the first electrode, the light emitting layer, and the second electrode. By the design of the drain line, the original shortest path of the first electrode lead region, the first electrode, the light emitting layer, the second electrode, and the second electrode lead region is blocked and allowed to pass around the lead line, that is to say, the shortest path is prolonged, which effectively affects the distribution of light emission uniformity and improves the brightness uniformity and the service life of the device.
