Diese Aufgabe wird gemäß der Erfindung durch die Merkmale des Kennzeichens des Patentanspruches 1 gelöst.This object is achieved according to the invention by the features of the characterizing part of patent claim 1.
Durch die beschriebene Bedeckung wenigstens des einen Polarisators mit einer optisch angekoppelten Schutzscheibe wird sowohl ein mechanischer als auch ein chemischer oder physikalischer Schutz des Polarisators bewirkt, ohne daß dadurch zusätzliche optische Beeinträchtigungen beim Betrachten der Plüssigkrislallzelle in Kauf genommen werden müßten. Zusätzlich wird durch die in optischem Kontakt aufgebrachte Schutzscheibe eine weitere Versteifung der genannten Flüssigkristallzelle erzielt. Die Schutzscheibe kann gleichzeitig als Halterungsteil beim Einbau der Zelle in ein Gerät dienen.By covering at least one of them as described Polarizer with an optically coupled protective pane is both a mechanical and a chemical or physical protection of the polarizer without causing additional optical impairment Consideration of the Plüssigkrislallzelle accepted would have to be. In addition, the protective pane, which is applied in optical contact, provides additional stiffening achieved the said liquid crystal cell. The protective screen can also be used as a mounting part Installation of the cell in a device are used.
Anhand des in der Figur schematisch im Querschnitt dargejij stellten Ausführungsbeispiels wird die Erfindung nachfolgend näher erläutert.Based on the dargejij in the figure schematically in cross section The invention is explained in more detail below.
Die Figur zeigt eine zwischen einem Betrachter 1 und einer Beleuchtungsquelle 2 transmissiv betriebene Flussigkristallzelle. Durch Anbringen eines mehr oder weniger teildurchlässigen Spiegels (Transflektors oder Reflektors) auf der dem Betrachter 1 abgewandten Seite der Zelle kann die Zelle auch transflektiv oder reflektiv betrieben werden, wobei im letzteren Falle die Beleuchtungsquelle 2 entfällt. The figure shows one between a viewer 1 and one Illumination source 2 transmissively operated liquid crystal cell. By attaching a more or less partially transparent mirror (transflector or reflector) the side of the cell facing away from the viewer 1, the cell can also be operated transflective or reflective, in the latter case the illumination source 2 is omitted.
Die Flüssigkristallzelle besteht aus einer zwischen den transparenten Trägern 3 und 4 angeordneten Flüssigkristallschicht 7· Die Träger 3 und 4 bestehen bevorzugt aus Glas. Sie weisen auf ihren Innenflächen als transparente Schichten ausgebildete Elektroden bzw. Elektrodenmuster 5 und 6 auf, mit deren Hilfe ein die optische Wirkung der Flüssigkristallschicht änderndes elektrisches Feld an diese Schicht 7 anlegbar ist. Auf den Außenflächen derThe liquid crystal cell consists of a liquid crystal layer arranged between the transparent substrates 3 and 4 7 · The carriers 3 and 4 preferably consist of Glass. They have electrodes or electrode patterns 5 designed as transparent layers on their inner surfaces and 6, with the aid of which an electric field which changes the optical effect of the liquid crystal layer is applied this layer 7 can be applied. On the outer surfaces of the

Träger 3 und 4 befinden sich Polarisationsfilter 8 und 9> die bevorzugt aus Folien bestehen, die in optischem Kontakt auf den Trägern 3 und 4 angeordnet sind.Carriers 3 and 4 are polarization filters 8 and 9> which preferably consist of foils which are arranged in optical contact on the carriers 3 and 4.
Gemäß der Erfindung ist nun auf wenigstens einen der Polfilter 8 und 9, insbesondere auf dem dem Betrachter zugewandten PolX'ilter 8 eine Schutzscheibe 10 in optischem Kontakt mit der Polarisationsfolie 8 aufgebracht. Diese Schutzscheibe 10 ist bevorzugt starr und besteht insbesondere aus einer Glasscheibe, die zusätzlich zu einer mechanischen Versteifung der Flüssigkristallzelle beiträgt und zweckmäßig als Halterungsteil für die Zelle dienen kann.According to the invention, at least one of the polarizing filters 8 and 9, in particular that of the viewer, is now on facing PolX'ilter 8 a protective pane 10 in optical Contact with the polarizing film 8 applied. These Protective pane 10 is preferably rigid and consists in particular of a glass pane, in addition to a mechanical stiffening of the liquid crystal cell contributes and expediently serve as a holding part for the cell can.
Die optische Ankopplung der Schutzscheibe 10 an das PoI-filer 8 erfolgt zweckmäßig mit einem optisch transparenten Kleber 11. Ein bekannter Kleber für solche optischen Ankopplungen ist beispielsweise ein unter dem Namen Kanadabalsam bekanntes Harz. Die freie Oberfläche der Schutzscheibe 10 ist zweckmäßig optisch entspiegelt und kann ggf. noch zusätzliche Schutzschichten gegen chemische Einflüsse aufweisen. Zur Halterung kann diese Zelle zusammen mit der aufgebrachten Schutzscheibe in einen entsprechenden Halterahmen eingegossen werden. Je nach Art der Halterung und des Betriebs der Zelle kann es auch zweckmäßig sein, auf dem rückwärtigen Polfilter 9 ebenfalls eine Schutzscheibe in optischem Kontakt mit dem !'ölfilter aufzubringen.The optical coupling of the protective pane 10 to the PoI filer 8 is expediently carried out with an optically transparent adhesive 11. A known adhesive for such optical couplings is for example a resin known as Canada balsam. The free surface of the protective screen 10 is expediently optically anti-reflective and can optionally have additional protective layers against chemical Have influences. This cell, together with the applied protective screen, can be placed in a corresponding one for holding purposes Holding frame are cast. Depending on the type of mounting and the operation of the cell, it can be appropriate, on the rear polarizing filter 9 also a protective screen in optical contact with the ! 'to apply the oil filter.
