Abstract: A polarized light extraction optical element is formed by a light-transmitting base material and a polarization separation layer laminated thereonto, this polarization separation layer being a liquid crystal layer made of a cholesteric liquid crystal. The thickness of the liquid crystal layer is smaller than the thickness that would be required to achieve a maximum reflectivity, so that part of one of the right and left circularly polarized light components is reflected with a reflectivity smaller than the maximum reflectivity.
