In accordance with the present invention, a method of electrophotographically manufacturing a luminescent screen assembly on an interior surface of a faceplate panel (12) of a color CRT (10) comprises the steps of coating the interior surface of the panel with a volatilizable, organic conductive material to form an organic conductive (OC) layer (32), and overcoating the OC layer with a volatilizable, photoconductive material to form an organic photoconductive (OPC) layer (34). Then, a substantially uniform voltage is established on the OPC layer, and selected areas of the OPC layer are exposed to visible light to affect the voltage thereon, without affecting the voltage on the unexposed area of the OPC layer. Next, triboelectrically charged, light-absorbing screen structure material is deposited onto the unexposed area of the OPC layer to form a substantially continuous matrix (23) of light-absorbing material having open areas therein. The present method is an improvement over prior methods in that the present method includes the additional steps of forming a planarizing layer (35, 135) on the OPC layer; overcoating the planarizing layer with a second coating of the volatilizable, organic conductive material to form a second OC layer (132), and then overcoating the second OC layer with a second coating of the volatilizable, organic photoconductive material to form a second OPC layer (134). The phosphor materials are deposited onto a suitable charged and exposed second OPC layer so that the phosphors completely overlie the openings in the matrix and overlap at least a portion of the matrix adjacent to the openings.
