  • Method for manufacturing a multi-domain liquid crystal cell
    Patent number: 6593986
    Abstract: A method for fabricating a multi-domain liquid crystal cell is disclosed, wherein first and second alignment directions are formed in first and second portions of an alignment layer provided on a substrate by selectively subjecting the first and second portions to different energy doses of linearly polarized ultraviolet light. Liquid crystal material is then injected between the one substrate and another substrate and into contact with the alignment layer, thereby obtaining a wide viewing angle in the liquid crystal device.
    Type: Grant
    Filed: July 1, 1998
    Date of Patent: July 15, 2003
    Assignee: LG Electronics Inc.
    Inventors: Soon Bum Kwon, Jong Hyun Kim, Oleg Yaroshchuk, Andrey Dyadyusha

  • Liquid crystal display device
    Patent number: 6572939
    Abstract: A liquid crystal display device comprises first and second substrates, an alignment layer including a pyranose polymer or a furanose polymer on at least one of the first and second substrates, and a liquid crystal layer between the first and second substrates. The liquid crystal display device is characterized by excellent thermostability, superior anchoring energy and uniform alignment of the liquid crystal achieved in a reduced treatment time without creating any flowing effect in the liquid crystal.
