第５図Figures 1 and 2 are a schematic diagram showing an embodiment of the present invention (applied to a color cathode ray tube) and a cross-sectional view of its main parts; FIG. 4 is a sectional view of essential parts showing another embodiment of the present invention (applied to a black and white cathode ray tube). 1 is a tube body, 1a is a glass panel, 2 is a color fluorescent surface, 3
1 is a color selection electrode, 6 is a lens portion, and 8 is a light absorber pattern. - 口χn口口口゛h ["Amended 1984. 111 The simple explanation of one page is amended as follows. '"It is a cross-sectional view" on page 8, line 7 of the specification is replaced with "a cross-sectional view. , FIG. 5, and FIG. 6 are a plan view and a sectional view of main parts showing other embodiments of the present invention.'' Correction 1982.11. 8. The scope of claims for utility model registration and the brief description of the drawings are amended as follows. O Utility Model Registration Claims A lens pattern with a refractive index distribution is formed in the front glass member facing the fluorescent surface of the cathode ray tube, and a lens pattern is formed on the outer surface of the glass member near the focal point of each of the lens parts. A cathode ray tube comprising a light absorber pattern having a light transmitting portion. BRIEF DESCRIPTION OF THE DRAWINGS FIGS. 1 and 2 are a schematic diagram showing one embodiment of the present invention (applied to a color cathode ray tube) and an enlarged sectional view of its essential parts;
Figures A to ■ are process diagrams showing an example of the manufacturing method of the front glass plate, Figures 4 and 5 are plan views and cross-sectional views showing other embodiments of the present invention, and Figure 6 is a process diagram showing an example of the manufacturing method of the front glass plate. Embodiment (applied to a black and white cathode ray tube), and FIGS. 7 and 8 are enlarged sectional views of essential parts showing still another embodiment of the present invention (applied to a color cathode ray tube) and its essentials. Enlarged sectional view of the section, Figure 9A~
(2) is a process diagram showing an example of the manufacturing method. 1 is a tube body, 1a is a glass panel, 2 is a color fluorescent surface, 6
8 is a light absorber pattern, and 23 is a front glass plate. 1 f 3tt 3m 3tx - Fig. 7 N - Fig. 4 Fig. 5
