    • An organic electroluminescent device is provided. The device includes a substrate, an anode, an emitting layer and a cathode. The anode is disposed on the substrate, the emitting layer is disposed on the anode, and the cathode is disposed on the emitting layer. The emitting layer is constructed by a dark-blue emitting layer/light-blue emitting layer/reddish orange emitting layer or a light-blue emitting layer/dark-blue emitting layer/reddish orange emitting layer. Since the dark-blue emitting layer has an excellent bright blue light color and high brightness, and the light-blue emitting layer has a long service life, and therefore, organic electroluminescent device of the present invention has an excellent blue light color, high brightness and long service life.
    • 提供有机电致发光器件。 该器件包括衬底,阳极,发光层和阴极。 阳极设置在基板上,发光层设置在阳极上,阴极设置在发光层上。 发光层由深蓝色发光层/浅蓝色发光层/红橙色发光层或浅蓝色发光层/深蓝色发光层/红橙色发光层构成。 由于深蓝色发光层具有优异的亮蓝色光和高亮度,并且发光层的使用寿命长,因此本发明的有机电致发光元件具有优异的蓝光色,高亮度 使用寿命长。
