ABSTRACT:
A fluorescent display panel has a luminescent structure on an insulating substrate, a grid structure over the luminescent structure and filaments over the grid structure in an inner space defined by a case member bonded to the insulating substrate by means of frit, and the frit is pushed out from the boundaries between the case member and the insulating substrate; photo-shield plates are provided between the luminescent structure and the boundaries, and are arranged in such a manner as to be in parallel to the boundaries so as to block light component radiated from the luminescent structure to the boundaries.
