1. A display panel comprising:
a base substrate; and
a pixel structure disposed on the base substrate, wherein the pixel structure comprises:
a first pixel electrode comprising a first main pixel area and a first sub-pixel area, wherein the first main pixel area and the first sub-pixel area are arranged in a second direction perpendicular to the first direction;
a second pixel electrode arranged in alternation with the first pixel electrode in a first direction and comprising a second main pixel area and a second sub-pixel area, wherein the second main pixel area and the second sub-pixel area are arranged in the second direction;
a transverse signal line located between the first main pixel area and the first sub-pixel area and extending in the first direction, wherein the transverse signal line is a scan signal line;
a first longitudinal signal line comprising a first main line and a first secondary-line extending along the second direction, wherein the first longitudinal signal line is a data signal line; and
