Abstract
A luminescent screen includes a plurality of columnar luminescent elements made of a transparent material which contains a substance capable of emitting luminescent light in response to stimulating light applied thereto, the columnar luminescent elements having central axes parallel to each other and having adjacent sides held against each other. Emitted luminescent light is prevented from leaking in a direction normal to the longitudinal direction of the columnar luminescent elements, thereby increasing the brightness of the entire luminescent screen. Since the columnar luminescent elements of the luminescent screen are not integrally joined as a continuous unitary structure, any leaking luminescent light from the adjacent luminescent elements or regions is reduced.
