PURPOSE: To improve luminance by filling the periphery of a dot or a stripe with metal excellent in heat conductivity and electric conductivity when forming a fluorescent film in dot or stripe shape on a glass substrate to make it into a luminous screen, and then covering the surface of the structure, being made this way, with an aluminum reflection film.
CONSTITUTION: On a glass substrate 1 being cleaned enough, a thin aluminum layer 2 by heating deposition in low vacuum and a thick aluminum layer 3 by heating deposition in high vacuum are stacked, and the light absorption factor of the layer 3 is made small beforehand. Next, the space surrounded by this laminate is formed by etching this laminate, and phosphors 4, 5 and 6 are stuffed in these spaces, respectively. Thereafter, the whole face of these phosphors and the laminate where the surfaces are exposed is covered with an aluminum film 7 being a reflective film, and is heat-treated at about 450°C into a fluorescent film. This way, a screen excellent in relative luminous output, luminance maintenance factor, nonelectrification factor, etc., is obtained easily.
