Method for preparing organic light-emitting display panel, organic light-emitting display panel, and display device

An organic light-emitting display panel, comprising:

• a substrate;
• a pixel defining layer, defining a plurality of sub-pixels on the substrate;
• and
• a light-emitting functional layer, located on a side of the pixel defining layer away from the substrate,
• wherein the light-emitting functional layer is provided with a disconnection slit at a gap between two adjacent sub-pixels,
• wherein the sub-pixels comprise a red sub-pixel, a green sub-pixel and a blue sub-pixel, and an orthographic projection of the disconnection slit on the substrate surrounds an area where the red sub-pixel is located,
• the orthographic projection of the disconnection slit on the substrate has a surrounding portion, a first connecting portion and a second connecting portion, the first connecting portion connects two surrounding portions that are adjacent in a first direction, the first connecting portion separates areas, where the green sub-pixel and the blue sub-pixel are located, in a second direction, the second connecting portion connects two surrounding portions that are adjacent in the second direction, and the second connecting portion separates areas, where the green sub-pixel and the blue sub-pixel are located, in the first direction, and
• all of the red sub-pixel, the green sub-pixel and the blue sub-pixel are hexagonal, the red sub-pixel, the green sub-pixel and the blue sub-pixel have different sizes from one another, the surrounding portion is hexagonal and surrounds the hexagonal red sub-pixel, and each of six sides of the hexagonal surrounding portion is parallel to a corresponding side of the hexagonal red sub-pixel, the first connecting portion is parallel to at least one side of the surrounding portion, and the second connecting portion is not parallel to any side of the surrounding portion.
