Abstract To eliminate an initial transition from splay to bend alignment, polymer‐stabilized OCB was developed. The influences of the monomer concentration and the applied voltage during UV irradiation were studied, and stable bend alignment in the absence of electric field was obtained. The large retardation change and the fast response were achieved by using a mixture of multifunctional LC acrylate monomers, and a 9‐inch full‐color polymer‐stabilized OCB TFT‐LCD with initial bend alignment and the contrast ratio of 250:1 was successfully developed.
