ABSTRACT:
A luminescent screen includes a screen plate containing a substance capable of emitting luminescent light in response to stimulating light applied thereto. The screen plate is made of a resin containing a planar assembly of hollow column-shaped members having sides thereof fixed together, the column-shaped members defining respective elements. Since light emission interference does not occur between the elements, the brightness of the screen is increased. The hollow column-shaped members in the screen plate make the screen mechanically strong.
