Abstract
A display panel includes: a first base substrate including sub-pixel areas; first light-emitting devices corresponding to the sub-pixel areas one by one; a first dam layer including first opening areas; first photoluminescent layers on a side of the first light-emitting devices away from the first base substrate and in at least part of the first opening areas; second light-emitting devices on a side of the first dam layer away from the first light-emitting devices; a second dam layer on a side of the second light-emitting devices away from the first base substrate and including second opening areas corresponding to the sub-pixel areas one by one; and second photoluminescent layers on a side of the second light-emitting devices away from the first base substrate and in at least part of the second opening areas. Orthographic projections of the second light-emitting devices do not overlap with the sub-pixel areas.
