Abstract:
A display device comprising:polarization axis varying means;first polarizing splitter means disposed on one side of said polarization axis varying means which transmits a light ray component linearly polarized in a first direction while reflecting or absorbing a light ray component linearly polarized in a predetermined direction different from said first direction;second polarizing splitter means disposed on another side of said polarization axis varying means which reflects a light ray component linearly polarized in a second direction while transmitting a light ray component linearly polarized in a predetermined direction different from said second direction;lighting means disposed on a side of said second polarizing splitter means opposite to said polarization axis varying means; andlight diffusing means disposed between said second polarizing splitter means and said lighting means which diffuses and reflects a light ray coming in from said second polarizing splitter means, while transmitting a light ray coming from said lighting means toward said second polarizing splitter means.
