1. A display panel, comprising:
a base substrate provided with a first display region and a second display region, wherein the first display region comprises a first sub-display region and a second sub-display region, and at least partially surrounds the second display region, the second sub-display region being proximal to a border of the base substrate relative to the first sub-display region;
a plurality of pixels separately disposed in the first display region and the second display region, wherein at least two pixels in the plurality of pixels comprise target electrodes and are separately disposed in the first display region and the second display region, a size of the target electrode disposed in the second display region being less than a size of the target electrode disposed in the first display region, and/or a density of the target electrodes disposed in the second display region being less than a density of the target electrodes disposed in the first display region; and
a packaging layer disposed on a side, distal from the base substrate, of the plurality of pixels, wherein the packaging layer comprises a first organic layer, and a difference between a maximum thickness and a minimum thickness of a first portion, disposed in the second display region, of the first organic layer being less than a difference between a maximum thickness and a minimum thickness of a second portion, disposed in the second sub-display region, of the first organic layer.
