Abstract
A method of making a liquid crystal display cell wherein the planar glass plates of the cell are bonded together with a photopolymerizable epoxy-containing material to form a hermetically sealed cell and wherein the photocured seal is chemically resistant to the contents of the liquid crystals cell. Adhesion of the photopolymerizable epoxy material to the glass plates of the liquid crystal cell is improved by addition of glycidoxypropyl triethoxy silane or its precondensate.
