  • Patent number: 5956001
    Abstract: An image display device of the present invention includes: a display element having pixels which are arranged in columns and rows and are grouped into a plurality of right eye pixel groups and a plurality of left eye pixel groups, each of the right eye pixel groups and the left eye pixel groups including at least one pixel; a driver which supplies driving signals to the right eye pixel groups and the left eye pixel groups independently; an optical member for making a polarization state of light exiting from the right eye pixel groups different from a polarization state of light exiting from the left eye pixel groups; and an array of microlenses which is disposed in the vicinity of the optical member, wherein each of the microlenses collimates light exiting from a corresponding one group of the right eye pixel groups and the left eye pixel groups.

  • Patent number: 5940156
    Abstract: A liquid crystal display device of the present invention includes: a liquid crystal region made of a liquid crystal as a display medium; and a polymer wall surrounding the liquid crystal region between a pair of substrates, wherein the polymer wall is formed by selectively radiating light having different irradiation intensities to an irradiation intensity-dependent mixture containing a photopolymerizable monomer.

  • Patent number: 5831703
    Abstract: A liquid crystal display device includes a pair of substrates provided with a plurality of pixels and a liquid crystal region formed of liquid crystal as a display medium, the liquid crystal region being interposed between the pair of substrates. A photosensitive film having birefringence is provided on at least one face on the liquid crystal region side of the substrates so as to surround at least one pixel.

  • Patent number: 5729312
    Abstract: The liquid crystal display device of the invention includes; a pair of substrates disposed so as to be opposed to each other; and a display medium interposed between the pair of substrates, the display medium having liquid crystal regions comprising one or a plurality of pixels, and the liquid crystal regions being surrounded by polymer walls, wherein a number of substrate gap control materials which are disposed in a gap between the pair of substrates is larger in the polymer walls rather than in the liquid crystal regions.

  • Patent number: 5621553
    Abstract: The liquid crystal display device of this invention, includes: a pair of substrates, at least one of which is transparent; and a liquid crystal layer including a plurality of polymer walls and liquid crystal regions surrounded by the plurality of polymer walls and being interposed between the pair of substrates, wherein each substrate includes a display section having a plurality of electrodes for display at a side adjacent to the liquid crystal layer and a non-display section provided around the display section, and wherein a polymer wall formation rate in the peripheral region of the display section is 90% or more.
