摘要： A display panel, a preparation method thereof and a display device. The display panel has a display area and anon-display area outside the display area. The non-display area includes: a first non-display area close to the display area, a second non-display area located on one side away from the display area, of the first non-display area, and a bent area between the first non-display area and the second non-display area. The bent area includes: a substrate and a first buffer layer located on the substrate. Materials of the first buffer layer include: a first doping element and a first insulation compound. The first doping element is used for improving ductility of the first buffer layer.

摘要： The present disclosure provides an organic electroluminescent display substrate, a method for fabricating the same, and a display device. The organic electroluminescent display substrate includes: a substrate; a circuit element on the substrate; a first insulating layer on a side of the circuit element away from the substrate and having at least one groove; a first conductive portion at least partially filled in the at least one groove and at least partially electrically coupled to the circuit element; a second insulating layer on a side of the first conductive portion away from the circuit element and covering the first insulating layer and the first conductive portion; and a light-emitting element on a side of the second insulating layer away from the first conductive portion.

摘要： A driving backplane includes: a substrate; a first conductive layer disposed on the substrate; an insulating layer disposed on a side of the first conductive layer away from the substrate; and a second conductive layer disposed on a side of the insulating layer away from the substrate. The first conductive layer includes a first electrode, the first electrode includes a first sub-electrode and a second sub-electrode surrounding the first sub-electrode, and the second sub-electrode and the first sub-electrode have no gap therebetween. The second conductive layer includes a second electrode. An orthographic projection of the second electrode on the substrate coincides with an orthographic projection of the first sub-electrode on the substrate. The first sub-electrode, the second electrode and a portion of the insulating layer located therebetween constitute a first capacitor.
