We propose the stabilization technique for the memory state of bistable liquid crystal (LC) mode in the pixel‐isolated LC (PILC) structure. To obtain the enhanced retention time of memory state, we apply the multi‐rubbing method to create the partial 90° twisted domains in each sub‐pixel as the seeds of stabilizing the π‐twist states. The PILC structure provides the uniform and stable cell gap against various external deformations. The suggested structure can be very useful for portable flexible display applications with high quality device performance such as low power consumptions and good mechanical reliability.
