The invention provides a display panel and a display device.The display panel comprises a substrate, an isolation structure, a plurality of light-emitting units and a first packaging layer, the isolation structure, the light-emitting units and the first packaging layer are located on the substrate, a plurality of first openings are defined by the isolation structure, and the isolation structure comprises a first isolation part and a second isolation part which are stacked in sequence; the orthographic projection of the first isolation part on the substrate is located in the orthographic projection of the second isolation part on the substrate, at least part of the light-emitting unit is located in the corresponding first opening, and the first packaging layer is located on the side, away from the substrate, of the light-emitting unit and covers the light-emitting unit and part of the isolation structure. The material of at least part of the first isolation part and the material of the first packaging layer are the same kind of materials, so that the adhesion between the first isolation part and the first packaging layer is enhanced, the first packaging layer and the first isolation part are tightly jointed and can form a closed loop, the packaging effect between the first packaging layer and the isolation structure is enhanced, and the packaging quality is improved. And the packaging effect, the service life and the display effect of the display panel are improved.

The utility model relates to the technical field of toy assembling structures, in particular to a toy assembling structure and a dessert cabinet toy, which comprise an upper part and a lower part assembled below the upper part, a lower assembling hole is formed in the center of the top wall of the lower part, a lower sinking groove is formed in the outer side of the lower assembling hole, the upper assembling part comprises a plurality of sets of buckling parts, and the buckling parts are connected with the lower portions of the top walls of at least two sides of the lower part in a clamped mode. A front-back dual-clamping structure is formed by clamping a first clamping fastener at the bottom of the upper part, a clamping bump at the top of the lower part, a second clamping fastener at the bottom of the upper part and the top wall of the lower part, so that the lateral torsion resistance of the cabinet body is remarkably enhanced in an up-and-down assembly mode, tight joint attachment is realized, and the service life of the toy is prolonged; and the assembling convenience and the long-term use stability are both considered.
