Abstract

Eine Flüssigkristallanzeige hat hinter einer Scheibe (1) aus Polymethylmethancryl zur Bildung mehrerer Anzeige­ felder mehrere, voneinander unabhängige Flüssigkristall­ zellen (4). Zwischen jeder Flüssigkristallzelle (4) und der Scheibe (1) ist jeweils ein schmaler Luftspalt (5) vorhanden, so daß Newtonsche Ringe vermieden werden. Die Scheibe (1) ist nur im Bereich der Anzeigefelder durch­ sichtig. A liquid crystal display has behind a pane (1) Made of polymethyl methane acrylic to form multiple displays fields several independent liquid crystal cells (4). Between each liquid crystal cell (4) and the disc (1) is a narrow air gap (5) available so that Newton's rings are avoided. The Disc (1) is only in the area of the display fields visible.
