Abstract
A method of controlling the spacing between the panels in large area liquid crystal cells consisting of the application of an array of spacer dots on one panel and an array of tie dots on the other panel. Upon firing the panels, the spacer dots remain rigid to define the spacing whereas the tie dots soften and deform.
