Abstract
An electroluminescent display panel and a display apparatus are provided. The display panel includes: a base substrate including a display region and a non-display region; an encapsulating structure on the base substrate, extending from the display region to the non-display region; and a crack dam structure on the base substrate, locating at an edge of the non-display region and on a side of the encapsulating structure away from the display region. The crack dam structure includes: an inorganic layer on the base substrate, including a plurality of dams and a plurality of slots, the dams and the grooves locating at an edge of a side of the inorganic layer away from the display region; and an organic layer, on the inorganic layer, covering at least the dams and fill the slots, wherein a surface of the organic layer away from the base substrate includes at least a non-planar structure.
