Flexible perovskite light‐emitting diodes (FPLEDs) that combine the superior optoelectronic properties of perovskites with the potential of highly flexible, stretchable, and portable electronics have emerged as a new class of revolutionary LED devices for various applications. This article focuses on the recent FPLED research and development. The flexible substrate and electrode are summarized, and the relationship between structure optimization and device performance is established. In order to improve the flexibility and optoelectronic characteristics of FPLEDs, some strategies are put forward, such as the optimization of flexible electrode and emissive layer, the interface engineering, the energy level adjustment, the improvement of light extraction, as well as the improvement of flexibility and stretchability. Furthermore, the future development of FPLEDs is prospected.
