Perovskite thin‐film electroluminescence devices are prepared, opening up a new optical application of perovskite materials. With increasing driving voltage, the intensity of electroluminescence increases dramatically. High‐quality red color is produced and the working voltage for whole‐surface electroluminescence is as low as 10 V.
