Abstract
A light-emitting device (42, 68, 80, 90, or 100) suitable for a flat-panel CRT display contains a plate (54), a light-emissive region (56), a light-blocking region (58), and a light-reflective layer (60 or 70). 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 (72, 82, 92, and 100) 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.
