Abstract
A PALC panel is filled with LC material by creating a partial vacuum in the LC space and a peripheral receiving space inward of an attachment bead which secures the lower substrate assembly to the upper substrate assembly and introducing sufficient LC material into the receiving space to fill the LC space. The receiving space is then sealed. The volume of the receiving space is substantially greater than the volume of the LC space.
