Abstract:
A display device, comprising:a variable transmission polarization axis means capable of varying a transmission polarization axis;a first polarized light separating means which is placed on one side of said variable transmission polarization axis means, which transmits light of a linearly polarized light component in a first direction and which reflects, of the light of a linearly polarized light component in a predetermined direction different from said first direction, a component in a wavelength region .DELTA..lambda. and transmits a component in a predetermined wavelength region different from said wavelength region .DELTA..lambda.; anda second polarized light separating means which is placed on another side of said variable transmission polarization axis means, which transmits light of a linearly polarized light component in a second direction, and which reflects or absorbs light of a linearly polarized light component in a predetermined direction different from said second direction.
