1. A display panel, comprising:
touch lines comprising at least one first touch line and at least one second touch line, wherein the at least one first touch line and the at least one second touch line are located in different layers; and
a first dielectric layer located between the at least one first touch line and the at least one second touch line,
wherein the display panel comprises a first region and a second region, a thickness A of the first dielectric layer in the first region in a direction perpendicular to a plane of the display panel, and a thickness B of the first dielectric layer in the second region in the direction perpendicular to the plane of the display panel satisfy: A>B>0, wherein in the second region, one of the at least one first touch line is electrically connected to one of the at least one second touch line through a via penetrating through the first dielectric layer, and a thickness of the via in the direction perpendicular to the plane of the display panel is smaller than a maximum thickness of the first dielectric layer both in the first region and in the second region in the direction perpendicular to the plane of the display panel.
