Field emission display devices of 100 mmϫ100 mmϫ2.4 mm in size are fully developed with the 80 cd/m 2 of brightness. Full color real images are characterized by using structural analysis and electron trajectory profiles. No cross talk between pixels is confirmed by a simulation and a process integration. As a reliable process integration, phosphor screening integration of full color phosphors and conditions of high vacuum packaging are extensively investigated as a basis of mass production. In addition, the electrical reliability with a phosphor effect due to an electron excitation is studied with a lifetime test at various condition. Especially, the stability inside narrow vacuum space between anode and cathode plates is fully demonstrated with various process control parameters.
