PROBLEM TO BE SOLVED: To provide a light source device using an electron emission light-emitting device superior in the effects of light emission, and provides a light emission method capable of easily manufacturing an electron emission light-emitting device, and a superior uniform light source which is low in manufacturing cost and superior in production rate. SOLUTION: The electron emission light-emitting device includes a cathode structure 220, an anode structure 210, a fluorescent layer 240, and a low-pressure gas layer 230. The fluorescent layer 240 is located between the cathode layer structure 220 and the anode layer structure 210. The low-pressure gas layer, filled between the cathode structure and the anode structure, has the function of inducing the cathode to emit electrons uniformly. The low-pressure gas layer has an electron mean fee path that allows at least an ample amount of the electrons to directly impinge the fluorescent layer under the operating voltage.
