Abstract
An electron emission light-emitting device includes a cathode structure, an anode structure, a fluorescent layer, and a low-pressure gas layer. The fluorescent layer is located between the cathode structure and the anode structure. The low-pressure gas layer is filled between the cathode structure and the anode structure, having a function of inducing the cathode to emit electron uniformly. The low-pressure gas layer has an electron mean free path, allowing at least sufficient amount of electrons to directly impinge the fluorescent layer under an operation voltage.
