Abstract
In one aspect, the invention encompasses a field emission display device. The device comprises a base plate and a face plate which is over and spaced from the base plate. The device further comprises emitters associated with the base plate and phosphor associated with the face plate. Additionally, the device comprises a reflector associated with the base plate and having an upper reflective surface.In another aspect, the invention encompasses a method of forming a field emission display device. A base plate is provided, and a pair of spaced emitter-containing regions are provided over the base plate. A reflector is formed over the base plate and between the spaced emitter-containing regions. A face plate is provided, and a pair of spaced phosphor-containing masses are formed in association with the face plate. The face plate and base plate are joined to one another with the face plate being aligned over the base plate and spaced from the base plate. After the joining, the spaced emitter-containing regions align under the spaced phosphor-containing masses, and the reflector aligns under the space between the spaced phosphor-containing masses.
