Abstract: Provided are a display panel, a preparation method thereof, and a display device. The display panel includes a plurality of sub-panels. Each sub-panel includes first substrate, second substrate, bezel adhesive located therebetween, a plurality of bank structures, and a plurality of light-emitting elements. At least one light-emitting element forms a pixel unit. Each bank structure is located between adjacent pixel units. Seaming adhesive is located between adjacent sub-panels. The sub-panels share a same first substrate, and the seaming adhesive is disposed on the same first substrate. The first substrate includes a display region and a non-display region surrounding the display region. The light-emitting elements and the bank structures are located in the display region, and the bezel adhesive is located in the non-display region. In this manner, splicing gaps between adjacent sub-panels can be effectively reduced, and thus the display effect of the display panel can be improved.
