Abstract: A pixel defining layer, a manufacturing method therefor, and a display panel are provided. The pixel defining layer comprises a first sub-defining layer, a light absorbing layer, and a second sub-defining layer sequentially stacked on a substrate. The light absorbing layer is used for absorbing light for exposing the first sub-defining layer. An orthographic projection of the light absorbing layer on the substrate covers the outer edge of an orthographic projection of the first sub-defining layer on the substrate away from the surface of the substrate.

Abstract: A pixel defining layer, a display substrate and manufacturing method thereof, and a display apparatus are provided. The pixel defining layer includes: a lyophilic material layer disposed on a base substrate, and a lyophobic material layer disposed at a side of the lyophilic material layer away from the base substrate. An orthographic projection of a surface of the lyophobic material layer close to the base substrate on the base substrate is within an orthographic projection of a surface of the lyophilic material layer away from the base substrate on the base substrate. The lyophilic material layer is made of a lyophilic material having attractability to a solution with organic electroluminescent materials dissolved, and the lyophobic material layer is made of a lyophobic material having repellency to the solution with organic electroluminescent materials dissolved. The pixel defining layer reduces the influence on the uniformity of the films.

Abstract: A pixel unit, a display panel, a display device and a method of manufacturing a pixel unit. The pixel unit includes a first sub-pixel unit and a second sub-pixel unit, each sub-pixel unit includes a first electrode, an emission layer, and a second electrode stacked on a substrate. An emission lifespan of the emission layer of the first sub-pixel unit is smaller than that of the emission layer of the second sub-pixel unit. An area of an orthographic projection of the emission layer of the first sub-pixel unit on the substrate is equal to that of the emission layer of the second sub-pixel unit on the substrate. An area of an orthographic projection of the first electrode of the first sub-pixel unit on the substrate is greater than an area of an orthographic projection of the first electrode of the second sub-pixel unit on the substrate.

Abstract: A pixel defining structure includes a first sub-pixel defining structure surrounding a first sub-pixel region configured to form a first sub-pixel having a first color. The first sub-pixel defining structure includes a lyophilic portion one the bottom side of the first sub-pixel region and a lyophobic portion on a side opposite to the bottom side. The pixel defining structure includes a second sub-pixel defining structure surrounding a second sub-pixel region configured to form a second sub-pixel having a second color. The second sub-pixel defining structure includes a lyophilic portion one the bottom side of the second sub-pixel region and a lyophobic portion on a side opposite to the bottom side. The second color is different from the first color. Thicknesses of the lyophilic portion of the first sub-pixel defining structure and the lyophilic portion of the second sub-pixel defining structure are different.
