Multilayer anode structures (104) for electronic devices (100) such as
polymer light-emitting diodes are described. The multilayer anodes
include a high conductivity organic layer (114) adjacent to the
photoactive layer (102) and a low conductivity organic layer (112)
between the high conductivity organic layer and the anode's electrical
connection layer (110). This anode structure provides polymer light
emitting diodes which exhibit high brightness, high efficiency and long
operating lifetime. The multilayer anode structure of this invention
provides sufficiently high resistivity to avoid cross-talk in passively
addressed pixellated polymer emissive displays; the multilayer anode
structure of this invention simultaneously provides long lifetime for
pixellated polymer emissive displays.
