  • Patent number: 4813768
    Abstract: A liquid crystal device having a higher durability and a display quality less likely to be degraded, for example, for use in a glare shield reflection mirror. The liquid crystal device comprises: a pair of substrate plates, a liquid crystal layer filled between the pair of substrate plates, and an oblique evaporation film laminated on one of the substrate plates, wherein a protective layer is formed on the boundary surface between the oblique evaporation film and a neighboring component member. The oblique evaporation film has become less susceptible to the neighboring material, and problems, such a bluish oblique evaporation film due to the proton (H.sup.+) intrusion from the neighboring material, have been prevented. Thus the liquid crystal device has come to have a higher durability and a display quality less likely to be degraded.
