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 arranged 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 or absorbs light of a linearly polarized light component in a direction different from said first direction;a second polarized light separating means which is arranged 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, of light of a linearly polarized light component in a predetermined direction different from said second direction, a component of a first wavelength region .DELTA..lambda.1 and transmits a component of a wavelength region -.DELTA..lambda.1 different from said first wavelength component; anda third polarized light separating means which is placed on a side opposite to said variable transmission polarization axis means with respect to said second polarized light separating means, which transmits light of a linearly polarized light component in a third direction, and which reflects, of light of a linearly polarized light component in a predetermined direction different from said third direction, a component of a second wavelength region .DELTA..lambda.2 and transmits a component of a wavelength region -.DELTA..lambda.2 different from said second wavelength component.
