Abstract:
In a base plate assembly including an insulative substrate for a luminescence display tube and grid supports formed on the substrate along side edges thereof, a plurality of protrusions are extended sideways from the body of the substrate beyond the grid supports. When each of the grid supports has a protrusion left after cutting of the supports from two frames, the protrusions of the substrate are extended beyond the protrusions of the grid supports.
