Abstract:
1. A liquid crystal display device comprising: a light source; a first polarizing plate disposed over the light source; a polarization control liquid crystal device comprising a liquid crystal layer interposed between a pair of transparent electrodes and divided into a plurality of stripe portions arranged in a first direction, the polarization control liquid crystal device being disposed over the first polarization plate and controlling an optical retardation of each of the stripe portions; an array of lenticular lenses disposed over the polarization control liquid crystal device so that lenticular lenses are arranged in the first direction; a first retardation plate disposed over the array of lenticular lenses and comprising a first stripe portions arranged in a second direction having a first optical retardation and a second stripe portions arranged in the second direction having a second optical retardation that is different from the first optical retardation, the first and second strip portions being arranged alternately; a liquid crystal panel disposed over the first retardation plate; a second polarizing plate and a third polarizing plate between which the liquid crystal panel is disposed; a second retardation plate having a third optical retardation and disposed between the first polarizing plate and the polarization control liquid crystal device; and a third retardation plate having the third optical retardation and disposed between the polarization control liquid crystal device and the first retardation plate.
