A green perovskite‐quantum‐dot (Per‐QD) light‐emitting diode with high efficiency and color purity was fabricated. This device exhibited a narrow spectrum with a half width of 19 nm and covered the BT.2020 color gamut. Improving an electron‐transport layer increased the external quantum efficiency to 6.2%.
