Abstract: Provided is a display panel, including a driver backplane, a pixel definition layer, a plurality of light-emitting devices, and a touch line. A plurality of openings are formed in the pixel definition layer. The light-emitting device includes a normal element and at least one privacy element, which are disposed in different openings. The touch line includes a first wiring and a second wiring. An orthographic projection of the first wiring on the driver backplane falls on a periphery of an orthographic projection of the opening, where the privacy element is disposed, on the driver backplane. A distance between an orthographic projection of the second wiring on the driver backplane and the orthographic projection of the opening on the driver backplane is greater than a distance between the orthographic projection of the first wiring on the driver backplane and the orthographic projection of the opening on the driver backplane.

Abstract: A display substrate comprises a base substrate that comprises a first display area provided with multiple sub-pixels of different colors. At least one sub-pixel comprises a light-emitting element and a pixel driving circuit for driving the light-emitting element to emit light. The light-emitting element comprises a first electrode, a second electrode, and an organic light-emitting layer provided between the first electrode and the second electrode. The first electrode is a reflective electrode and is electrically connected to the pixel driving circuit. A first structure is provided on a side of the first electrode of the light-emitting element of a sub-pixel of at least one target color close to the base substrate, and a surface of the first structure close to the first electrode is uneven.
