Abstract
This invention offers a liquid crystal display device with which each of a plurality of observers can visually recognize each of two different images displayed on a single liquid crystal display panel respectively. The liquid crystal display device of this invention includes a light source for backlighting, a first polarizing plate to extract linearly polarized light from the light source for backlighting, a polarization control LCD composed of a liquid crystal layer divided into a plurality of columns and controlling an optical retardation of each of the plurality of columns, lenticular lenses disposed along the columns, a first retardation plate in which a row having a first optical retardation and a row having another optical retardation that is different from the first optical retardation are disposed alternately, a display LCD and a second and a third polarizing plates between which the display LCD is interposed.
