Abstract
A method and apparatus for producing a liquid crystal display (LCD) whereby the two planar cell wall elements of the LCD are separated by an adhesion web made of a preparation which is polymerized into a solid, transparent adhesive bonding by the application of actinic radiation. The two planar cell wall elements, one of which is provided with the web preparation are mounted in a device which guides the cells toward one another. Upon reaching a predetermined measured separation distance, the cells are exposed to a source of actinic radiation, thereby polymerizing the web preparation into a suitable adhesion bonding between the two planar display elements.
