    Abstract: The halide perovskite blue light emitting diodes (PeLEDs) attracted many researchers because of its fascinating optoelectrical properties. This review introduces the recent progress of blue PeLEDs which focuses on emissive layers and interlayers. The emissive layer covers three types of perovskite structures: perovskite nanocrystals (PeNCs), 2-dimensional (2D) and quasi-2D perovskites, and bulk (3D) perovskites. We will discuss about the remaining challenges of blue PeLEDs, such as limited performances, device instability issues, which should be solved for blue PeLEDs to realize next generation displays.
