Abstract :
The spontaneous formation of self-aligned multidomains is used for fabricating wideviewing liquid crystal displays (LCDs) based on dielectric surface patterns (DSPs). The periodic DSPs can be produced on substrates through either the curing of photopolymers or the replica molding of dielectric polymers. Due to the symmetric multidomain structure associated with the initial liquid crystal (LC) director distribution, the LC cells with the periodic DSPs are found to show high contrast and wideviewing characteristics.
