Abstract: A display panel and a display device are provided. The display panel includes a plurality of pixels. A pixel of the plurality of pixels includes a light-emitting layer, and the plurality of pixels include at least one first pixel and at least one second pixel. A first pixel is electrically connected to a first pixel circuit, and a second pixel is electrically connected to a second pixel circuit. An orthographic projection of the first pixel circuit on a plane of the display panel has an area smaller than an orthographic projection of the second pixel circuit on the plane of the display panel. In a direction perpendicular to the plane of the display panel, a light-emitting layer of the first pixel at least partially overlaps the second pixel circuit, and a light-emitting layer of the second pixel at least partially overlaps the second pixel circuit.

Abstract: A display panel, a fabrication method of the display panel, and a display apparatus are provided in the present disclosure. The display panel includes a substrate; a drive substrate on the substrate, where the drive substrate includes a first film layer; and the first film layer includes a first opening; and a light-emitting element on the drive substrate, where the light-emitting element is disposed corresponding to the first opening. The drive substrate further includes an auxiliary film layer; and the auxiliary film layer includes a thickened part, a thinned part, or a hollow part overlapped with the first opening.

Abstract: A display panel includes a substrate, an array layer, an optical layer, and a plurality of light-emitting devices. The array layer is on the substrate. The optical layer and the plurality of light-emitting devices are located on a side of the array layer away from the substrate. The optical layer is arranged corresponding to intervals between light-emitting devices of the plurality of light-emitting devices.
