1. A display panel, having a display area and a bezel area, and comprising:
a first support structure located in the display area and comprising a plurality of first support portions;
an encapsulation adhesive located in the bezel area and extending along an edge of the display area; and
a second support structure located in the bezel area and extending along the edge of the display area, and located on a side of the encapsulation adhesive that faces towards the display area;
wherein at different positions of the bezel area, the second support structure and the encapsulation adhesive are at an equal distance from each other within a preset error range; the second support structure comprises at least one second support portion; and
in a direction perpendicular to a plane in which the display panel is located, an orthographic projection area of each of the at least one second support portion is larger than an orthographic projection area of a first support portion of the plurality of first support portions;
the bezel area comprises a first sub-area and a second sub-area, the first sub-area has a width W11 in a direction perpendicular to an extension direction of the first sub-area, the second sub-area has a width W12 in a direction perpendicular to an extension direction of the second sub-area, and W11<W12; and
the second support structure in the first sub-area has a width W21 in a direction perpendicular to an extension direction of the second support structure in the first sub-area, the second support structure in the second sub-area has a width W22 in a direction perpendicular to an extension direction of the second support structure in the second sub-area, and W21<W22;
wherein the display panel is an organic light-emitting diode display panel; and
wherein the second support structure is in contact with the first support structure adjacent to the second support structure to form a third support structure, the third support structure extends along the edge of the display area, and comprises adjacent first sub-support structure and second sub-support structure, in a direction from the encapsulation adhesive towards the third support structure, a width of the first sub-support structure is greater than a width of the second sub-support structure.
