Abstract
A 3-dimension facet light-emitting source device including a transparent container, an anode plate, a cathode plate, a plurality of transparent plates and a low-pressure gas layer is provided. The transparent container has a sealed space. The transparent plates are disposed between the anode plate and the cathode plate, and have a fluorescent layer thereon respectively. The lower pressure gas layer is filled in the sealed space to induce electrons emitting from the cathode plate, and the electrons fly in a direction parallel to the transparent plates and hit each fluorescent layer to emit light, so as to form a set of 3-dimension facet patterns.
