We have previously reported that dual frequency driven PDLC exhibits electrically reversible switching in a time for practical applications without sticking. The device retains the memory state even after removal of the driving voltage. This bistable memory switching is remarkably enhanced by a high concentration of bi‐functional prepolymers, which leads to a smaller and uniform morphology of polymer‐balls. As a result, the memory state shows a higher contrast. For a flexible type of the display, a thick resist, which is originally issued in micromechanics technology, is well applicable as the gap spacer on a plastic substrate. This simplifies the fabrication process.
