    Abstract: An electroluminescent layer according to the present invention comprises a core-shell particle comprising a perovskite crystal core and a shell of a dielectric polymer, wherein a charge transfer pathway to the perovskite crystal core is formed by dielectric breakdown of the dielectric polymer. The electroluminescent layer according to the present invention can prevent the deterioration of perovskite crystals due to external moisture, oxygen, or the like since the perovskite crystal core is enclosed and protected by the dielectric polymer and can have improved charge transfer and injection efficiencies since charges are directly transferred and injected to the perovskite crystals through the charge transfer pathway formed by dielectric breakdown of the dielectric polymer.
