Liquid crystal display device with which a plurality of observers can visually recognize each of two different images displayed on a single LCD panel

摘要

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 (11) to extract linearly polarized light from the light source for backlighting, a polarization control LCD (20) composed of a liquid crystal layer divided into a plurality of columns (21,22) and controlling an optical retardation of each of the plurality of columns (21,22), lenticular lenses (30) disposed along the columns (21,22), a first retardation plate (40) 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 (50) and a second and a third polarizing plates (12,13) between which the display LCD (50) is interposed.
