Abstract
In active semiconductor backplane ( ), for example for a smectic liquid crystal cell, which comprises an array of electronic or elctrical elements in a first region ( ), logic elements for addressing said array in a second region spaced from the first, and conductors coupling said first and second regions, the first and second regions are sufficiently widely spaced ( ) (providing a “glue lane”) to permit the presence of an adhesive sealing strip therebetween without substantial contact with the first and/or second regions, even when an opposed substrate is sealed thereto. The backplane may comprise spacers ( ) in the first region and/or glue lane.
