ABSTRACT:
In a method forming a phosphor layer on a screen panel, the black matrix is made of a conductive material. The conductive black matrix is formed by a wet-layer photoconductive method. That is, an organic conductive layer is initially deposited on the screen panel, then an organic photoconductive material is formed on the organic conductive layer. The plotoconductive layer is charged to a positive or negative potential and a selective area of the organic photoconductive layer is exposed to light radiated from an exposure device, such that the potential can be left on the unexposed area where the black matrix will be deposited. Finally, the conductive black matrix material is deposited on the unexposed area.
