摘要： Provided are a display panel and a manufacturing method thereof and a display device. The display panel includes: a base substrate; a pixel defining layer including first openings defining sub-pixels; an encapsulation layer; and a light modulation layer. The light modulation layer is configured such that light from each of at least one sub-pixel propagates along a direction away from the base substrate after total reflection upon incidence on an interface between the first light modulation portion in a corresponding second opening and the first light modulation sub-layer. The display panel satisfies at least one of a first condition or a second condition. The first condition is that at least a part of edge of the first orthographic projection has a recess. The second condition is that at least a part of edge of the second orthogonal projection has at least one of a recess or a protrusion.

摘要： The invention provides an organic electroluminescent device and a manufacturing method thereof, and a display apparatus. The method for manufacturing the organic electroluminescent device of the invention includes using the following to form at least one function layer: preparing a solution of a material of the function layer, and forming a liquid material layer for the function layer using the solution of the material of the function layer; performing a vacuum drying on the liquid material layer for the function layer to form function layer. In the invention, a relatively dense film is formed by performing a vacuum drying on the function layer, and the residual organic solvent is effectively removed to avoid the formation of defects, so that the film becomes smooth and dense, which increases the carrier mobility in the film and is advantageous to the transport and recombination of electrons and holes.
