Abstract
A luminescent screen includes a screen plate containing a substance capable of emitting luminescent light in response to stimulating light applied thereto, and a regular array of convexes on one surface of the screen plate for trapping emitted luminescent light that is directed into the screen plate and for directing the trapped luminescent light toward a display surface of the screen plate. The brightness of the display surface is therefore increased.
