LIGHT-EMITTING PANEL AND PREPARATION METHOD THEREFOR, AND LIGHT-EMITTING APPARATUS

A light-emitting panel and a preparation method therefor, and a light-emitting apparatus, which relate to the technical field of illumination and display. The light-emitting panel has a light-emitting area (A) and an isolation area (L) adjacent to the light-emitting area (A). The light-emitting panel comprises a base substrate (1) and a barrier structure (8), wherein the barrier structure (8) is arranged on one side of the base substrate (1) and located in the isolation area (L), and comprises a first isolation pattern (81), a second isolation pattern (82), a third isolation pattern (83) and a fourth isolation pattern (84), which are sequentially arranged in a stacked manner, and the first isolation pattern (81) is closer to the base substrate (1) than the fourth isolation pattern (84); and an orthographic projection of the first isolation pattern (81) on the base substrate (1) is located in an orthographic projection of the second isolation pattern (82) on the base substrate (1), an orthographic projection o
