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.
