PURPOSE:To provide a cathode ray tube having excellent anode current (Ib)- luminance output (Bo) property and developing well-balanced color, prepd. by using a specified phosphor as blue illuminant. CONSTITUTION:A blue phosphor consisting of (A) zinc sulfide phosphor activated with silver and chlorine (ZnS:Ag, Cl) and (B) lanthanum oxychloride phosphor activated with thulium (LaOCl:Tm) is used as blue phosphor for a cathode ray tube for color image display which employs a combination of red, green and blue phosphors. Y2O3:Eu and LaOCl:Tb are used as red and green phosphors, respectively.
