Abstract
A polarized electroluminescent light-emitting panel is made by treating the photo-alignable functional group of the polymer hole transporting layer with a first direction and second direction photo-alignment treatment to have the molecules of the hole transporting layer aligned in specific directions and then forming a polymer emitting layer on the hole transporting layer, and thus a thin type full-color polarized electroluminescent light-emitting device that will produce polarized superimposition (3D image) is thus obtained.
