ABSTRACT:
A first polarization control element POL1provided on an outer surface of an array substrate AR and a second polarization control element POL2provided on an outer surface of a counter-substrate CT control a polarization state of light that passes therethrough, such that light in a polarization state of elliptically polarized light is to be incident on the liquid crystal layer LQ. An ellipticity of elliptically polarized light, which is incident on the liquid crystal display panel LPN in a principal viewing-angle direction is greater than an ellipticity of elliptically polarized light, which is incident in a anti-principal viewing-angle direction.
