Abstract

A method of manufacturing microstructure array, a microstructure array, a micro-light-emitting diode, and a method for manufacturing the same, and a display device. The method of manufacturing microstructure array includes: preparing a red light-emitting perovskite precursor solution, a green light-emitting perovskite precursor solution, and a blue light-emitting perovskite precursor solution; coating the red light-emitting perovskite precursor solution, the green light-emitting perovskite precursor solution, and the blue light-emitting perovskite precursor solution, on a substrate having partitioned first, second, and third regions to form a red light-emitting perovskite precursor film, a green light-emitting perovskite precursor film, and a blue light-emitting perovskite precursor film, respectively; disposing a mold having a plurality of concave micropatterns on the red light-emitting perovskite precursor film, the green light-emitting perovskite precursor film, and the blue light-emitting perovskite precursor film, respectively; heat-treating the red light-emitting perovskite precursor film, the green light-emitting perovskite precursor film, and the blue light-emitting perovskite precursor film in a plurality of concave micropatterns to obtain each of red light-emitting perovskite nanocrystals, green light-emitting perovskite nanocrystals, and blue light-emitting perovskite nanocrystals, and removing the mold to form a microstructure array.
