TN liquid crystal cell, whose twisting angle is azimuthally distributed, is fabricated by combing azimuthal and normal rubbing substrates. The molecular orientation state with twisting angle up to ±90° is stable state, and it transits to that with the twisting angle up to 180° after applying sufficiently high voltage although the state is metastable. The ±180° twisting cell can apply to the polarization converting device to create radial polarization.
