Abstract
Described is an optical compensator device that can maintain a high degree of performance in the demanding environment of projection display. A mounting process involves using a sealant between optically clear glass or ceramic substrate and low elastic polymer retarder film. The sealant may mitigate or prevent the degradation of the retarder film by acting as an oxygen barrier that seals the substrate and increases the lifetime of the device in high luminance.
