摘要:
The solution of the salt of the polymer electrolyte is used as a dispersant in the dispersion solution containing the pigment and used for forming the first layer (30B, 30G, 30R), and the substance which forms a salt along with the polymer electrolyte is mixed into the solution applied on the pigment layer (30B, 30G, 30R) and used for the second layer, and/or the developing solution. The formed layers are patterned and thus a display screen is obtained.

The shadow mask of a colour cathode ray tube is arranged in the vicinity of a phosphor screen. The shadow mask is provided with through-holes that select the electron beams emitted from the electron guns. A layer comprising, as a filler, one or other of a metal, metal oxide, metal carbide, metal nitride, or a mixture of two or more of these, for example zirconium powder and, as a binder, one of an amorphous metal oxide compound, amorphous metal hydroxide compound or a mixture of these, for example silicon oxide, is formed on the surface of the shadow mask. This layer increases thermal radiation of the shadow mask, reduces electron scattering, and raises the residual emissivity.

In a colour picture tube (1,2,3) having a phosphor screen (5) composed of a blue-emitting phosphor, a green-emitting phosphor, and a red-emitting phosphor, the ratio A/B of the brightness A of the red-emitting phosphor to the brightness B of the blue-emitting phosphor is 1.40 or more. Thus, red colour purity is improved without a decrease of the brightness of the phosphor screen. Consequently, a colour picture tube with a wide color reproducible region can be provided.
