  • Polymide-free alignment layer for LCD fabrication and method
    Patent number: 6841654
    Abstract: An inexpensive polyimide-free alignment layer comprising a mixture of an epoxy and a reactive liquid crystal material is used for fabricating liquid crystal displays (LCDs). The alignment layer can be cast onto a previously aligned layer, without destroying the alignment of the underlying layer, thus allowing for monolithic fabrication of compensator stacks, without film transfer lamination.
    Type: Grant
