Abstract

PURPOSE: To improve contrast without reducing the brightness of a screen by simply making a glass face plate absorb light and coloring a phosphor.
CONSTITUTION: The absorption spectra of the glass face plate 2 on which fluorescet layers R, G, and B are coated have their maximum value among the maximum values of the absoption spectra of the respective fluorescent layers R, G, and B. The light reflected on the fluorescent screen 4 in the extraneous light 3 from the outside of the face plate 2 goes into the component which corresponds to the emission pectra of the respective fluorescent layers R, G, and B. As a result, the contrast is improved.
