Title: Liquid crystal cell

Abstract: A liquid crystal cell is made by covering a wafer with an electrode system. A second insulating and transparent wafer is covered with a second system of semi-transparent electrodes. A wall of controlled thickness is deposited on a wafer around a periphery thereof. A metallic thread is deposited on a wafer with the same perimeter as the wall. The wafers are applied to each other and heated to fuse the thread on the top of the wall to join and seal the wafers with a liquid crystal between them within the wall.
