Abstract
A first polarization control element POL1 provided on an outer surface of an array substrate AR and a second polarization control element POL2 provided 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.
Claims15
A liquid crystal display device including a reflection section and a transmission section in each of a plurality of pixels arranged in a matrix, the device comprising:
- a liquid crystal display panel in which a liquid crystal layer is held between a first substrate and a second substrate that are disposed to face each other;
- a first polarization control element provided on an outer surface of the first substrate, which is opposed to a surface of the first substrate that holds the liquid crystal layer;
- and
- a second polarization control element provided on an outer surface of the second substrate, which is opposed to a surface of the second substrate that holds the liquid crystal layer,
- wherein the first polarization control element and the second polarization control element 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, and
- an ellipticity of elliptically polarized light, which is incident on the liquid crystal display panel 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.
