The invention discloses an electroluminescent device and a manufacturing method thereof. The electroluminescence device comprises a first electrode layer with transmittance, a second electrode layer with reflectivity, and a light-emitting layer arranged between the first electrode layer and the second electrode layer, and also includes a For the adjacent second electrode layer contact layer, the contact surface between the second electrode layer and the second electrode layer contact layer is a rough surface. In the present invention, the contact surface (i.e. the reflective surface) between the second electrode layer and the contact layer of the second electrode layer in the electroluminescent device is directly set as a rough surface, and the rough surface is covered with numerous depressions and protrusions, whether it is Whether it is concave or convex, the surface plasmon wave only propagates in the tangential direction of its contour line, which limits the propagation of the surface plasmon wave, and the propagation distance of the surface plasmon wave is greatly shortened, thereby effectively reducing the attenuation of reflected light energy degree. |
