Encapsulation structure, substrate and display panel

A substrate, comprising a base and an encapsulation structure, the encapsulation structure being located on the base, the encapsulation structure comprising:

• an encapsulation layer, comprising a first encapsulation layer and a second encapsulation layer, wherein the first encapsulation layer and the second encapsulation layer are sequentially laminated on the base, the first encapsulation layer is located on a first main surface of the second encapsulation layer;
• and
• a transition layer, juxtaposed with the first encapsulation layer on the first main surface;
• wherein the first main surface includes a first region in contact with the first encapsulation layer and a second region in contact with the transition layer, the second region is located at an edge of the first main surface, and a bonding strength between the transition layer and the second encapsulation layer is greater than a bonding strength between the first encapsulation layer and the second encapsulation layer.
