An organic electroluminescent panel includes several sub-pixels. The
sub-pixels include at least one first electrode; at least one shadow wall
formed at the periphery of the first electrode; at least one first common
layer formed on the first electrode; several emission layers
independently formed on the first common layer; at least one second
common layer formed on the emission layers; and at least one second
electrode formed on the second common layer. During the fabricating
process, the first, second, and third color evaporation sources are
provided independently for forming the first, second, and third color
emission layers on the corresponding region of first electrode. The tilt
directions of three color evaporation sources and the evaporation angles
between the evaporation source and the substrate surface are determined
according to the positions and heights of the shadow walls.
