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.

Display substrate and preparation method therefor, display device, and color filter substrate

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.
