ABSTRACT:
A two-sided fluorescent indicator panel is disclosed which uses two multilayer base plate assemblies, each of them being constituted such that a grid is attached on the multilayer base plate formed by stacking the required functional layers on a base plate, and being mutually opposingly disposed with their grid-attached sides facing each other; and one or a plurality of filaments disposed between the two base plate assemblies. According to the present invention, the structure of the device becomes simple, and the manufacturing process becomes also simple, thereby making it possible to produce a light, miniature, power-saving digital indicator panel.
