Nematic liquid crystals confined inside cubic scaffolds made by two-photon polymerization exhibit bistability and large memory effects in response to electric fields, due to topological defects interacting with the solid structure. When viewed through crossed polarizers, the pixels, which are initially bright, remain dark after the application of strong electric fields.
