ABSTRACT:
A lenticular luminescent screen includes a lenticular base plate made of a transparent material which contains a substance capable of emitting luminescent light in response to stimulating light applied thereto. The lenticular base plate having at least one surface composed of a plurality of adjacent partly cylindrical lens elements. Since the cylindrical lens elements can catch stimulating light with a higher efficiency, the luminescent screen can emit an increased intensity of luminescent light. Inasmuch as the luminescent screen is reduced in thickness between the adjacent cylindrical lens elements, emitted luminescent light is prevented from leaking in a direction across the axes of the cylindrical lens elements.
