  • 3-dimensional image display device including a patterned retarder
    Patent number: 9791726
    Abstract: A stereoscopic three-dimensional image display device is disclosed which includes: a liquid crystal display panel defined into a plurality of pixel regions; a data driver to supply data voltages to the pixel regions; a patterned retarder disposed on a front surface of the liquid crystal display panel to polarize light from the liquid crystal display panel. The patterned retarder includes a first patterned retarder, to circularly polarize light from the liquid crystal display panel in a first direction and formed in a height greater than that of a pixel region of the plurality of pixel regions, and second patterned retarder to circularly polarize light from the liquid crystal display panel in a second direction opposite the first direction and formed in a height greater than that of the pixel region.
