1. A polarizing element comprising:

  • a layer including liquid crystal molecules; and

    a polarizer having a transmission axis, wherein the liquid crystal molecules have a chiral smectic texture of a helical configuration, an axis of a molecular helix of the helical configuration of each of the liquid crystal molecules is along a direction other than a direction normal to a surface of the layer, and a direction of an orthogonal projection of the axis onto the surface of the layer is substantially at 90°

    with respect to the transmission axis of the polarizer.
