The surface of self‐constructed molecular density modulation (SDM) exhibits a wide range of liquid crystal alignment capabilities including planar, tilted, and homeotropic alignments, disclination‐free uniform and heterogeneous alignments, and even spatially varying alignments through the single non‐contact process. Alignment defects are eliminated by temporary lowering the frictional energy barrier via the open‐boundary elastic stabilization (OES) treatment.
