Cancer immunotherapy using anti‐programmed death‐ligand 1 (PD‐L1) antibodies has been used in various clinical applications and achieved certain results. However, such limitations as autoimmunity, tumor hyperprogression, and overall low patient response rate impede its further clinical application. Mounting evidence has revealed that PD‐L1 is not only present in tumor cell membrane but also in cytoplasm, exosome, or even nucleus. Among these, the dynamic and spatial heterogeneous expression of PD‐L1 in tumors is mainly responsible for the unsatisfactory efficacy of PD‐L1 antibodies. Hence, numerous studies focus on inhibiting or degrading PD‐L1 to improve immune response, while a comprehensive understanding of the molecular mechanisms underlying spatial heterogeneity of PD‐L1 can fundamentally transform the current status of PD‐L1 antibodies in clinical development. Herein, the concept of spatial heterogeneous expression of PD‐L1 is creatively introduced, encompassing the structure and biological functions of various kinds of PD‐L1 (including mPD‐L1, cPD‐L1, nPD‐L1, and exoPD‐L1). Then an in‐depth analysis of the regulatory mechanisms and potential therapeutic targets of PD‐L1 is provided, seeking to offer a solid basis for future investigation. Moreover, the current status of agents is summarized, especially small molecular modulators development directed at these new targets, offering a novel perspective on potential PD‐L1 therapeutics strategies.
