1. A display panel, comprising:
a main display region and a display light transmission region; and
a substrate and a pixel definition layer disposed on a side of the substrate;
wherein the pixel definition layer defines a plurality of first pixel openings in the main display region and a first light-emitting layer is provided on each first pixel opening, and the pixel definition layer defines a plurality of second pixel openings in the display light transmission region and a second light-emitting layer is provided on each second pixel opening;
wherein the first light-emitting layer is all disposed in the first pixel opening, an edge of the second light-emitting layer overflows the second pixel opening, and the second light-emitting layer covers the second pixel opening and the pixel definition layer disposed in the display light transmission region;
wherein a size of the first pixel opening is greater than a size of the second pixel opening, and a ratio of an orthographic projection area of the first light-emitting layer projected on the substrate to an orthographic projection area of the second light-emitting layer projected on the substrate ranges from 95% to 105%;
wherein a first anode and a second anode are disposed on the substrate;
wherein the main display region comprises a plurality of first pixel units, and the display light transmission region comprises a plurality of second pixel units, each of the plurality of first pixel units comprises a plurality of first sub-pixels, and each of the plurality of second pixel units comprises a plurality of second sub-pixels;
wherein a ratio of a light-emitting pixel area of each of the plurality of second sub-pixels to a light-emitting pixel area of each of the plurality of first sub-pixels having a same color ranging from 0.2 to 0.6; and
wherein a ratio of an area of the second anode corresponding to each of the plurality of second sub-pixels to an area of the first anode corresponding to each of the plurality of first sub-pixels having a same color ranging from 0.2 to 0.6.
