    • Provided is a white light emitting organic electroluminescent device, which includes a transparent substrate, a first element, and a second element. The first element includes a first anode, a first element organic layer, and a reflective cathode sequentially disposed on a first substrate of the transparent substrate. The second element includes a second anode, a second element organic layer, and a transparent or translucent cathode sequentially disposed on a second surface of the transparent substrate. The white light emitting organic electroluminescent device of the present invention can eliminate the color coordinates shift phenomenon of white light that occurs in a conventional three primary color white light organic electroluminescent device. Since the aging effect caused by heat generated from light emission is reduced by dividing electroluminescent layers, the electroluminescent device can have a long lifespan.
    • 提供一种白色发光有机电致发光器件,其包括透明基板,第一元件和第二元件。 第一元件包括顺序地设置在透明基板的第一基板上的第一阳极,第一元件有机层和反射阴极。 第二元件包括顺序地设置在透明基板的第二表面上的第二阳极,第二元件有机层和透明或半透明阴极。 本发明的白色发光有机电致发光元件能够消除在现有的3原色白光有机电致发光元件中发生的白光的色坐标偏移现象。 由于通过分割电致发光层而减少由发光产生的热引起的老化效应,因此电致发光器件可以具有长的寿命。
