Abstract
An alignment layer for a liquid crystal on silicon (LCOS) display includes a nano-particle layer. In a particular embodiment the nano-particle layer includes a lower nano-layer and an upper nano-layer, each formed onto oxide layers of the LCOS display. In a more particular embodiment, the lower nano-layer and the upper nano-layer are offset printed onto the oxide layers.
