Dielektrisches Interferenz-Filtersystem, LCD-Anzeige und CCD-Anordnung sowie Verfahren zur Herstellung eines dielektrischen Interferenz-Filtersystems und Verwendung des Verfahrens

摘要

A dielectric interference filter comprises two filter elements 3 of different spectral characteristics on the same carrier substrate 1. The filter elements 3 have the same height and preferably adjoin each other without gaps. The system is used for, inter alia, interference colour filter systems in the form of LCD-displays or CCD-arrangements. A process for manufacturing the system includes forming at least one filter element (BG) by coating and subsequent etching, and forming at least one subsequent filter element (R) by coating and a subsequent lift-off operation in which the etching mask is used as the lift-off mask.
