An organic electro-luminescent (EL) device is provided. The present invention
discloses that the number of moisture-absorbing channels is increased to prevent
the generation of dark spots and to improve the luminescence quality of the organic
EL device. The organic electro-luminescent (EL) device comprises: a substrate;
at least a bottom electrode, formed on the substrate, a plurality of isolation
ribs for moisture-absorption and insulation, formed on a surface of the bottom
electrode, intersecting the bottom electrode, wherein regions between every two
of the isolation ribs are pre-determined light-emitting regions; at least an organic
layer comprising an organic electro-luminescent layer, formed on a surface of the
bottom electrode in the pre-determined light-emitting region; and at least an opposed
electrode, formed on a surface of the organic layer. The isolation ribs are formed
of PSG for removing the moisture generated during the processing of the organic
EL device so as to prevent the generation of dark spots. Furthermore, the isolation
ribs are helpful to achieve fine patterns of the device and avoid display crosstalk.
