We used patterned electric fields to produce polymer walls in twisted nematic (TN) and electrically controlled birefringence (ECB) displays. Application of a patterned field to a mixture of liquid crystal (LC) and monomer results in segregation of liquid crystal into the high field (pixel) regions and monomer into the low field (inter‐pixel) regions. Subsequent UV polymerization produces polymer walls surrounding the pixels. With proper selection of materials, uniform alignment of the liquid crystal can be obtained, resulting in good electro‐optic performance.
