In this study, a novel VA structure named Push‐pull VA (PPVA) was proposed and applied to 26 inch LCD‐TV, which has the advantages of high transmittance, Omni viewing angle and low cost. The disclination lines, which appear when the domain guiding structure (protrusion or ITO slit) in the CF substrate of the traditional VA device was removed, were eliminated significantly by adopting the push‐pull structure, and we succeed to enlarge the electrode space to 32um to get a larger aperture area.
