Display panel and fabrication method therefor, and display device

A fabrication method for a display panel, comprising:

• providing a substrate;
• forming a plurality of first electrodes on the substrate;
• forming isolation structures having a plurality of isolation openings on the substrate, the isolation openings respectively corresponding to the first electrodes;
• and fabricating light-emitting functional layers, second electrodes, and encapsulation units covering the isolation openings at the isolation openings in batches on the basis of the isolation structures, wherein the first electrode, the light-emitting functional layer and the second electrode stacked at each of the isolation openings form a light-emitting device, the encapsulation unit corresponding to each of the isolation openings forms a first encapsulation layer, and the first encapsulation layer is configured to form an encapsulation structure,
• wherein each of the light-emitting devices and a portion of the encapsulation structure covering the light-emitting device form a microcavity structure, and the light-emitting functional layers, the second electrodes and the corresponding encapsulation units of the light-emitting devices emitting light of different colors are fabricated in different batches on the basis of the isolation structures, wherein the microcavity structures corresponding to the light-emitting devices emitting light of different colors are different.

A display device, comprising:

• a display panel, comprising:
• a substrate;
• a plurality of light-emitting devices located on the substrate;
• isolation structures located on the substrate and comprising a plurality of isolation openings, at least part of film layers of the light-emitting devices being located in the isolation opening;
• and
• encapsulation structures located on sides of the isolation structures away from the substrate and covering the light-emitting devices,
• wherein each of the light-emitting devices and a portion of the encapsulation structure covering the light-emitting device form a microcavity structure, and the light-emitting devices emitting light of different colors correspond to different microcavity structures.
