Abstract:
1. 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 including homogeneously oriented liquid crystal molecules 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, an ellipticity of light with a wavelength of 550 nm, which is in the polarization state of elliptically polarized light, is between 0.5 and 0.85, and a difference between a maximum value and a minimum value of the ellipticity of light in the wavelength range of 450 nm to 650 nm in the polarization state of the elliptically polarized light incident on the liquid crystal layer is less than 0.15.
