Display panel, display device and fabricating method of display panel

A display device, comprising a display panel, wherein the display panel comprises:

• a base substrate;
• a first electrode layer and a second electrode layer on a side of the base substrate;
• a light-emitting layer between the first electrode layer and the second electrode layer;
• and
• a carrier functional layer located at least one of between the first electrode layer and the light-emitting layer, and between the second electrode layer and the light-emitting layer;
• wherein
• the light-emitting layer has a plurality of light-emitting portions with different emergent light wavebands;
• and
• the carrier functional layer has a plurality of carrier functional portions corresponding to the plurality of light-emitting portions, the plurality of carrier functional portions having molecular chains, which is formed by cross-linking of monomers containing functional groups under light irradiation.

A fabricating method of a display panel,

• the carrier functional layer has a plurality of carrier functional portions corresponding to the plurality of light-emitting portions, the plurality of carrier functional portions having molecular chains, which is formed by cross-linking of monomers containing functional groups under light irradiation.
• the method comprising:
• providing the base substrate;
• forming the first electrode layer and the second electrode layer on the side of the base substrate;
• forming the light-emitting layer between the first electrode layer and the second electrode layer;
• forming the carrier functional layer located at least one of between the first electrode layer and the light-emitting layer, and between the second electrode layer and the light-emitting layer;
• wherein
• forming the carrier functional layer located at least one of between the first electrode layer and the light-emitting layer, and between the second electrode layer and the light-emitting layer comprises:
• forming a light-emitting functional film containing functional groups at least one of between the first electrode layer and the light-emitting layer, and between the second electrode layer and the light-emitting layer;
• irradiating the light-emitting functional film containing the functional groups shielded by a patterning mask, to allow the functional groups in the light-emitting functional film irradiated by light to be cross-linked with each other;
• and
• cleaning the light-emitting functional film in a solution, to make portions not irradiated by light, of the light-emitting functional film be dissolved in the solution and removed.
