A method of manufacturing a color thin film electroluminescent display apparatus includes steps of: forming anodes consisting of an ITO on a transparent support substrate; forming a hole transporting layer thereon; carrying the substrate on a substrate holder within a vacuum evaporation device; placing a shadow mask, in which a side surface of opening sections has a taper, between the substrate and first, second and third resistance heat boats; evaporating a green electroluminescent material by means of the first heat boat and forming a green luminous layer on the substrate; evaporating a blue electroluminescent material by means of the second heat boat and forming a blue luminous layer on the substrate; successively, evaporating a red electroluminescent material by means of the third heat boat and forming a red luminous layer on the substrate; and thereafter, forming cathodes on the luminous layers. |
