Memorization of the alignment of nematic liquid crystals in electric fields is achieved by incorporating small amounts of self‐assembled fibers into the liquid crystals. Hydrogen‐bonded fibers formed in electrically aligned nematic phases direct liquid‐crystal alignment after removal of the electric fields (see Figure and cover). Rewritable bistable nematics of light‐scattering and transparent states have been achieved by a combination of thermal and electric stimuli.
