<p>A polarizing element 20 includes a cholesteric layer 21 that selectively reflects either one of right-handed and left-handed circularly polarized components of incident light, and an absorptive elliptical polarizing plate 22 that is laminated to the cholesteric layer 21. The polarizing plate 22 transmits elliptically polarized light that contains as its main component the circularly polarized component having the direction of optical rotation that is identical to that of the circularly polarized component selectively reflected by the cholesteric layer 21. In this polarizing element 20, the angle (angle of lamination) which the direction of the major axes of liquid crystalline molecules aligned on the absorptive-elliptical-polarizing-plate-side surface of the cholesteric layer 21, d1, forms with the direction of the major axis of elliptically polarized light produced by the absorptive elliptical polarizing plate 22, d2, falls in a specified angle range centering around 90 DEG . <IMAGE></p> |
