1. A display panel, comprising a first display area and a second display area, wherein a light transmittance of the first display area is greater than a light transmittance of the second display area, the first display area comprises a translucent sub-area, and a transition sub-area between the translucent sub-area and the second display area, and the display panel further comprises:
a drive substrate;
a first electrode layer located on a side of the drive substrate;
a light emitting layer located on a side of the first electrode layer away from the drive substrate, wherein the light emitting layer comprises a plurality of first pixels disposed in the first display area and a plurality of second pixels disposed in the second display area; and
a second electrode layer located on a side of the light emitting layer away from the first electrode layer;
wherein in the first display area, the second electrode layer is provided with a first opening between adjacent first pixels of the plurality of first pixels, center points of a plurality of adjacent first pixels around the first opening define a first polygon, and a ratio of an area of the first opening to an area of a corresponding first polygon ranges from 50% to 95%; and
wherein the drive substrate comprises:
a substrate;
a drive circuit layer disposed between the substrate and the light emitting layer, wherein the drive circuit layer comprises a plurality of first transistors corresponding to the plurality of first pixels, a plurality of second transistors corresponding to the plurality of second pixels, and a plurality of first signal traces electrically connected to the plurality of first transistors;
a light shielding layer disposed between the substrate and the drive circuit layer, wherein the light shielding layer comprises:
a plurality of first light shielding portions disposed corresponding to the plurality of first pixels;
a plurality of second light shielding portions disposed in the first display area and overlapped with the plurality of first signal traces, and each of the plurality of second light shielding portions is electrically connected between the adjacent first light shielding portions; and
a third light shielding portion disposed around the plurality of first light shielding portions and the plurality of second light shielding portions;
wherein the third light shielding portion and the transition sub-area at least partially overlap, and each of the plurality of second light shielding portions is further connected between the third light shielding portion and the plurality of first light-shielding portions adjacent to the third light shielding portion.
