Abstract
A light-emitting device ( , or ) suitable for a flat-panel CRT display contains a plate ( ), a light-emissive region ( ), a light-blocking region ( ), and a light-reflective layer ( or ). The light-emitting device achieves one or more of the following characteristics by suitably implementing the light-reflective layer or/and providing one or more layers ( , and ) along the light-reflective layer: (a) reduced electron energy loss as electrons pass through the light-reflective layer, (b) gettering along the light-reflective layer, (c) reduced secondary electron emission along the light-reflective layer, (d) reduced electron backscattering along the light-reflective layer, and (e) reduced chemical reactivity along the light-reflective layer.
