Abstract: The present disclosure provides an organic electroluminescent device and a display panel. The organic electroluminescent device includes a first electrode, a second electrode and a light-emitting layer disposed between the first electrode and the second electrode; a functional electrode is disposed on a side of at least one of the first electrode and the second electrode away from the light-emitting layer; the functional electrode includes a first layer-stacked structure including a plurality of first light-transmitting layers and at least one second light-transmitting layer; the first and second light-transmitting layers are stacked alternately; in the first layer-stacked structure, both the layer closest to the light-emitting layer and the layer farthest from the light-emitting layer are the first light-transmitting layers; a refractive index of the first light-transmitting layer is greater than a refractive index of the second light-transmitting layer.

Abstract: A display substrate includes an underlaying substrate, a display structure layer arranged on the underlaying substrate, and a light regulation layer arranged at a light exiting side of the display structure layer. The display structure layer includes multiple sub-pixels. An orthographic projection of the light regulation layer on the underlaying substrate does not overlap with opening regions of the multiple sub-pixels. The light regulation layer is configured to adjust an emergent direction of light of at least one color emitted from the display structure layer.
