Abstract:
A display device, comprising:a first polarization separator that transmits therethrough linearly polarized light polarized in a first direction and that does not transmit therethrough linearly polarized light polarized in a direction perpendicular to the first direction;a polarization changing element, disposed at a position to receive the linearly polarized light from said first polarization separator, that selects between a state in which a polarization direction of light transmitted therethrough is changed and a state in which the polarization direction is not changed;a second polarization separator, diametrically opposed to said first polarization separator with said polarization changing element interposed therebetween, that transmits linearly polarized light polarized in the first direction and reflects linearly polarized light polarized in a direction perpendicular to said first direction, the surface of said second polarization separator facing said polarization changing element being a smooth surface that reflects light in specular reflection;a first optical element;a light scattering layer laminated on the first optical element; anda light emitting element laminated on the light scattering layer, the light scattering layer scattering light on a surface of the light emitting element.
