Abstract:
A display device comprising:variable transmission polarization axis means capable of varying a transmission polarization axis; first polarized light separating means which is arranged on one side of the variable transmission polarization axis means and which allows light that is a linear polarized light component in a first direction to be transmitted and reflects or absorbs light that is a linear polarized light component in a predetermined direction different from the first direction; second polarized light separating means which is arranged on another side of the variable transmission polarization axis means and which allows light that is a linear polarized light component in a second direction to be transmitted and reflects light that is a linear polarized light component in a predetermined direction different from the second direction; a polarizer arranged on an opposite side of the variable transmission polarization axis means with respect to the second polarized light separating means; and a light source which is arranged on an opposite side of the second polarized light separating means with respect to the polarizer and which applies light to the variable transmission polarization axis means side, wherein a positional relationship between the second polarized light separating means and the polarizer is determined such that the second direction is deviated by a predetermined angle &thgr; (30Â°
