Light‐emitting diodes (LEDs) based on solution‐processed metal halide perovskites have shown great application potential in energy‐efficient lighting and displays. Multiple‐quantum‐well (MQW) perovskites simultaneously possess high photoluminescence quantum efficiency and good film morphology and stability, making it attractive for high‐performance perovskite LEDs. Here, merits of MQW perovskites and the progress in MQW perovskite LEDs are reviewed. Challenges and future directions of perovskite LEDs are also discussed.
