1. A display panel, comprising:
a plurality of first sub-pixels, a plurality of second sub-pixels and a plurality of third sub-pixels; wherein the first sub-pixel comprises a first light-emitting device which comprises a first effective light-emitting region; the second sub-pixel comprises a second light-emitting device which comprises a second effective light-emitting region; and the third sub-pixel comprises a third light-emitting device which comprises a third effective light-emitting region;
in a row direction, the plurality of first effective light-emitting regions form a plurality of first rows of effective light-emitting regions, and the plurality of second effective light-emitting regions and the plurality of third effective light-emitting regions are alternately arranged to form a plurality of second rows of effective light-emitting regions; the first rows of effective light-emitting regions and the second rows of effective light-emitting regions are alternately arranged in a column direction perpendicular to the row direction; a virtual quadrilateral is formed by lines connecting geometric centers of gravity of four first effective light-emitting regions in two adjacent rows and two adjacent columns;
a geometric center of gravity of the second effective light-emitting region and a geometric center of gravity of the third effective light-emitting region are located in corresponding virtual quadrilaterals respectively;
the second effective light-emitting region comprises at least one first curved edge, and/or the third effective light-emitting region comprises at least one second curved edge;
wherein a shape of the first effective light-emitting region is a rectangle or a rectangle with rounded corners; and
wherein long sides of the first effective light-emitting regions in a same column are located on a same straight line or parallel to each other.
