1. the polarization switch of the linearly polarized light of the initial polarization orientation of conversion, described polarization switch comprises:

  • The first liquid crystal cell, described the first liquid crystal cell has the first axis of orientation with respect to described initial polarization orientation;

    The second liquid crystal cell, described the second liquid crystal cell has the second axis of orientation with respect to described initial polarization orientation;

    AndAt least one first layer of compensation, described at least one first layer of compensation is between the first side of described the first liquid crystal cell and described the second liquid crystal cell, and described the first layer of compensation can operate to improve the visual field by described polarization switch.
