Abstract

A COLOR CATHODE RAY TUBE IS DISCLOSED, THAT COMPRISES AN OPTICAL FILTER LAYER 2 FORMED ON AN INNER SURFACE OF A GLASS PANEL 1, A THIN FILM FORMED ON A FRONT SURFACE OF THE OPTICAL FILTER LAYER 2 AND COMPOSED OF A METAL OXIDE, AND A FLUORESCENT SUBSTANCE LAYER 4 FORMED ON THE THIN FILM 3 CORRESPONDING TO A PATTERN OF THE OPTICAL FILTER LAYER 2. THE SURFACE STATE OF THE THIN FILM 3 IS ROUGHER THAN THE SURFACE STATE OF THE OPTICAL FILTER LAYER 2 AND SIMILAR TO THE SURFACE STATE OF THE FLUORESCENT SUBSTANCE LAYER 4. THUS, THE OPTICAL FILTER LAYER 2 SPARSELY CONTACTS THE FLUORESCENT SUBSTANCE LAYER 4. THUS, THE INFLUENCE OF THE OPTICAL FILTER LAYER 2 TO THE FLUORESCENT SUBSTANCE LAYER 4 CAN BE REDUCED. CONSEQUENTLY, FLUORESCENT SUBSTANCE PARTICLES OF THE FLUORESCENT SUBSTANCE LAYER 4 CN BE SUPPRESSED FROM BREAKING, DROPPING, AND SO FORTH. THUS, AN EXCELLENT FLUORESCENT SURFACE CAN BE OBTAINED AT HIGH THROUGHPUT.
