1. A display panel comprising a first display area and a second display area at least partially surrounding the first display area, a light transmittance of the first display area being greater than a light transmittance of the second display area, the second display area comprising:
a light-emitting element layer comprising a plurality of sub-pixels disposed in an array; and
a pixel circuit layer being arranged with a plurality of pixel circuits in one-to-one correspondence with the plurality of sub-pixels and comprising a plurality of intermediate film layers for forming transistors in the pixel circuits, the plurality of intermediate film layers being arranged in a stacked manner and insulated from each other, each of the intermediate film layers comprising a plurality of modules disposed to be insulated from each other, each of the modules comprising functional parts for forming the transistors and non-functional parts for connecting two adjacent functional parts, the functional parts are disposed in a different layer from the non-functional parts, and the non-functional parts and the two adjacent functional parts are electrically connected by vias.
