We exemplify an effective design principle for mass-producible 2D material-based super-barriers for flexible displays: fabrication by scalable layer-by-layer assembly process, low defect density, tortuous nanostructure, 100 % surface coverage, hydrophobization, and van der Waals gap narrowing. These design principles consistently stem from one simple rule: blocking all possible diffusion pathways.
