Quantum Rod Light‐Emitting Diodes In article number 2101204, Changhee Lee, Jeongkyun Roh, and co‐workers demonstrate polarized electroluminescence (EL) emission in high‐performance quantum rod (QR) light‐emitting diodes (LEDs). By employing the Langmuir‐Blodgett technique, they successfully produce a highly dense QR film with a high degree of alignment. As a result, the fabricated QR‐LEDs exhibit excellent device performance while accomplishing polarized EL emission. This work exhibits a promising potential in the development of solution‐processable polarized LEDs.
