Light-shielding screen device

摘要

A light-shielding screen device comprising a first light transmissible substrate, a second light transmissible substrate and an intermediate layer sandwiched therebetween, the intermediate layer comprising at least one light-shielding screen portion located in the middle area of the intermediate layer and a light non-transmissible retaining portion located at least in a portion of the remaining area of the intermediate layer, the portion of the remaining area including the entire outermost peripheral area of the intermediate layer. The light non-transmissible retaining portion of the intermediate layer of the present light-shielding screen device securely retains on its both sides the first and second light transmissible substrates, respectively. The present light-shielding screen device can be advantageously used not only as a light-shielding screen for television receivers, various displays having a CRT related to computers and the like in which a high mechanical strength of the light-shielding screen device is not necessarily required but also as an indicator means for push button type switches mounted on, e.g., an instrument panel of an automobile in which switches the light-shielding screen device is required to have a high mechanical strength.
