Perovskite light‐emitting diodes (LEDs) have emerged as new‐generation electroluminescent devices. By using quasi‐2D perovskite/PEO composite thin films as the light‐emitting layer, in article number 1707093 , Biwu Ma and co‐workers report highly efficient spectrally stable red perovskite LEDs with a state‐of‐the‐art maximum brightness of around 1400 cd m −2 and a peak external quantum efficiency exceeding 6.2%.
