1. A display panel, comprising:
a first substrate and a second substrate which are disposed opposite each other; and further comprising:
a plurality of light-emitting elements disposed on the first substrate and a plurality of baffle wall structures disposed on the second substrate, wherein the plurality of light-emitting elements and the plurality of baffle wall structures are located between the first substrate and the second substrate, and each baffle wall structure of the plurality of baffle wall structures is located between adjacent ones of the plurality of light-emitting elements; and
a plurality of first auxiliary structures, wherein the plurality of first auxiliary structures are disposed between the first substrate and at least a part of the plurality of light-emitting elements,
wherein the plurality of first auxiliary structures and gaps overlap in a direction parallel to the first substrate, and each of the gaps is a space between a respective one of the plurality of baffle wall structures and the first substrate;
wherein in a direction perpendicular to a plane on which the first substrate is located, each first auxiliary structure comprises a first surface and a second surface which are disposed opposite each other, and the first surface is a surface of each first auxiliary structure facing towards the first substrate; each first auxiliary structure further comprises a sidewall which connects the first surface to the second surface;
each of at least one first auxiliary structure is provide with a notch structure which comprises a first end, a second end and a concave surface which connects the first end to the second end;
wherein the concave surface is recessed inward away from a corresponding baffle wall structure along a direction of the corresponding baffle wall structure pointing to a respective one of the plurality of light-emitting elements;
the first end is located on the sidewall, the second end is located on the first surface, and the second end is located on a side of the first end away from the corresponding baffle wall structure; or
the first end is located on the first surface, the second end is located on the second surface, the sidewall is the concave surface, and the second end is located on a side of the first end away from the corresponding baffle wall structure.
