METHOD FOR FORMING FLUORESCENT SCREEN OF COLOR CATHODE-RAY TUBE

PURPOSE: A method for forming a fluorescent screen capable of improving color purity of a fluorescent screen by minimizing the residual quantity of different color phosphor is provided which improves brightness and color purity. CONSTITUTION: A method comprises the formation of a black mattress (10), three color phosphor layers and an aluminium film (12) in order, wherein a pigment particle layer is formed on the surface of every phosphor layer of the three color phosphor layers corresponding to each color using a pigment particle with the same color which is smaller than a phosphor comprising each phosphor layer. The average particle size of each pigment used in each pigment particle layer is less than 1 micrometer. The method has the advantages of exhibiting excellent brightness and color purity by allowing each pigment layer to serve for a filter.
