[0029] Example
[0030] This embodiment provides an organic electroluminescent device, including a substrate and a first electrode, a light-emitting layer 3, and a second electrode 4 that are sequentially stacked on the substrate; the first electrode includes a stacked electrically controlled birefringent material The film layer and a number of conductive film layers, the conductive film layers are not entirely arranged on the same side of the electrically controlled birefringent material film layer 2. Preferably, as figure 1 As shown, in this embodiment, the first electrode includes a first conductive film layer 11, a second conductive film layer 12, and a third conductive film layer 13 that are stacked, and the electrically controlled birefringent material film layer 2 is sandwiched Between the second conductive film layer 12 and the third conductive film layer 13.
[0031] The second electrode layer 4 is selected from, but not limited to, a stacked structure of one or more la...
