Abstract
The invention discloses an organic electroluminescent display panel, a manufacturing method thereof and a display device. A pixel defining structure comprises at least two pixel defining layers which are arranged in a laminated mode, the pixel defining layer away from a substrate base plate is arranged on the outer side of the pixel defining layer of an adjacent substrate base plate in a wrapping mode, the refractive index of the pixel defining layer away from the substrate base plate is higher than that of the pixel defining layer of the adjacent substrate base plate, therefore, according to the principle that total reflection can occur in light when the light irradiates to an optically thinner medium from an optically denser medium, when lateral light emitted by an organic electroluminescent structure irradiates a pixel structure, the lateral light with the incident angle being larger than the critical angle of total reflection can generate total reflection so as to enable the lateral light irradiating to the pixel structure from the organic electroluminescent structure to be reflected to the outside, and the phenomena of light leakage and light color interference of the organic electroluminescent display panel are avoided. Due to the fact that the lateral light is not prone to being absorbed by the pixel defining structure, the light-emitting efficiency of the organic electroluminescent display panel is increased.
