ABSTRACT:
An optical element of the invention comprises at least two laminated layers of reflective polarizer; and at least one retardation layer for changing polarization properties laminated between the reflective polarizers, the combination of the layers being designed so as to provide a incident-light transmittance depending on an incident angle of an incident light and designed such that a shielded light is not absorbed but reflected. The optical element can effectively shield transmitted lights with respect to obliquely incident lights and can control coloring.
