Embodiment 1
[0035] combine figure 1 and Figure 7 As shown, the embodiment of the present application provides a light-emitting device and a display panel. The display panel is equipped with the light-emitting device. The light-emitting device includes a substrate 100. The substrate 100 is formed with a pixel area that emits light of one color. The group of the first electrode layer 200, the organic functional layer 300, the second electrode layer 400, and the light-exiting layer 500, the group of the light-exiting layer 500 includes the first coupling layer 510 and the second coupling layer 520 whose refractive index is smaller than the first coupling layer 510, the second A coupling layer 510 and the second coupling layer 520 are located on the same layer and adjacent to each other, thereby dividing the pixel area into two light output areas, the first coupling layer 510 is located in one of the light output areas, and the second coupling layer 520 is located in the other light output a...
Embodiment 2
[0040] combine figure 2 and Figure 7 As shown, the embodiment of the present application provides a light-emitting device and a display panel. The display panel is equipped with the light-emitting device. The light-emitting device includes a substrate 100. The substrate 100 is formed with a pixel area that emits light of one color.
