A light-emitting panel has a light-emitting region and a non-light-emitting region, and at least one portion of a boundary of the light-emitting region is zigzag-shaped. The light-emitting panel includes: a base substrate, sub-pixels disposed in the light-emitting region on the base substrate: a first encapsulation layer disposed on a side of the plurality of sub-pixels away from the base substrate, and at least one first barrier wall disposed on the first encapsulation layer. Orthogonal projections of the sub-pixels on the base substrate are within an orthogonal projection of the first encapsulation layer on the base substrate. The first barrier wall is located in the non-light-emitting region, and is disposed at a side of the at least one zigzag-shaped portion of the boundary of the light-emitting region proximate to the non-light-emitting region. A refractive index of the first barrier wall is greater than a refractive index of the first encapsulation layer.
