Optical device with combined alignment and anisotropic layers
First Claim
1. An optical device comprising an anisotropic layer containing anisotropic molecules, and an alignment layer adjacent said anisotropic layer, said alignment layer serving to align the anisotropic molecules in an adjacent surface region of said anisotropic layer, wherein the alignment layer incorporates a twisted molecular structure so as to define a twisted optical retarder, the twisted molecular structure being provided by incorporating at least one of chiral molecules, chiral dopant and polymerized reactive mesogens having a twist, into the alignment layer.
