  • LIQUID CRYSTAL DISPLAY DEVICE, AND METHOD FOR PRODUCING THE SAME
    Publication number: 20010055088
    Abstract: A liquid crystal display device of the present invention includes: a first substrate and a second substrate; a liquid crystal layer interposed between the first substrate and the second substrate; and a vertical alignment layer provided on at least one of the first substrate and the second substrate on a side which is closer to the liquid crystal layer. The liquid crystal layer includes a plurality of liquid crystal regions partitioned by at least one partition wall provided on the first substrate on a side which is closer to the liquid crystal layer. The liquid crystal layer has a liquid crystal material with a negative dielectric anisotropy. Liquid crystal molecules in the plurality of liquid crystal regions are oriented in a direction substantially perpendicular to the first substrate and the second substrate in an absence of an applied voltage.
    Type: Application
