Abstract:
A polarizing apparatus for polarizing incident light having planes of polarization to light having a particular plane of polarization, comprising:an optically active material disposed so as to exhibit anisotropy with respect to the optical activity; wherein said optically active material increases the intensity of luminous flux having said particular plane of polarization and reduces the intensity of luminous flux having a plane of polarization perpendicular to the particular plane of polarization; wherein said optically active material comprises optically active molecules, and three-dimensional orientations of said optically active molecules are aligned in order to produce the anisotropy with respect to the optical activity; and wherein each of said optically active molecules comprises a rigid molecule portion, a chiral center joined thereto, and at least one substituent joined to said chiral center, wherein the direction from said rigid molecule portions to said chiral centers are substantially aligned in the same direction, and the three-dimensional orientations of said substituents seen from said chiral centers are aligned in substantially the same direction.
