Abstract
The disclosure provides methods and materials for decreasing the cost and increasing the efficiency of electroluminescent devices. The disclosure also provides electroluminescent devices prepared by such methods. In one embodiment, for example, there is provided a method for preparing an electroluminescent device comprising two metal electrodes, an electroluminescent layer, an optical/insulating layer, and a conductive layer, all of which are disposed on a transparent substrate. One of the electrodes is patterned, and the optical/insulating layer comprises vias to allow conduction between the patterned electrode and the conductive layer.
