A step‐shaped electrode design is proposed for Polymer Stabilized Blue Phase (PSBP) Transflective LCD (TR‐LCD). This new electrode design is capable of delivering very high optical efficiency (both T and R) of > 95% with operation voltage of ∼ 13V (or > ∼ 90% with ∼ 9V). The step‐shaped electrode helps generate strong horizontal electric fields across the whole cell and suppress the formation of dead zone.
