Abstract:
1. A polarized electroluminescent light-emitting panel fabrication method comprising the steps of: (a) preparing a substrate and forming a transparent conducting film on the surface of said substrate, said transparent conducting film being comprised of a anode pattern having a plurality of anodes; (b) making a plurality of upwardly extended ribs in between said anodes to form a retaining wall pattern; (c) using a polymeric hole transporting material having a photo-alignable functional group to make a hole transporting layer in between said ribs; (d) processing said hole transporting layer with a photo-alignment and crosslinking process properly in a first direction and a second direction to have the molecules of said hole transporting layer aligned in said first direction and said second direction; (e) coating polymer light-emitting materials on the alignment and crosslink-treated hole transporting layer to form an emitting layer; and (f) forming a metal cathode layer on said emitting layer.
