Abstract
A field emission device includes a first substrate, a second substrate spaced apart from the first substrate, a cathode structure formed between the first substrate and the second substrate for emitting electrons toward the second substrate, a luminescent layer formed between the first substrate and the second substrate for providing light when the electrons impinge thereon, and a reflecting layer formed between the second substrate and the luminescent layer for reflecting the light toward the first substrate.

A field emission device, comprising:
- a first substrate;
- a second substrate spaced apart from the first substrate;
- a cathode structure formed between the first substrate and the second substrate for emitting electrons toward the second substrate;
- a luminescent layer formed between the first substrate and the second substrate for providing light when the electrons impinge thereon;
