Abstract
A method for forming a display device, comprising: depositing a thin-film transistor switch circuit on a substrate; depositing by ink-jet printing an electrode layer of light transmissive conductive organic material in electrical contact with the output of the thin-film transistor circuit; and depositing an active region of the device over the electrode layer.

A method for forming a display device, comprising the steps of:
- depositing a thin-film transistor switch circuit having an output on a substrate;
- depositing by ink-jet printing an electrode layer of light transmissive conductive organic material in electrical contact with the output of the thin-film transistor circuit;
- and
- depositing an active region of the device over the electrode layer.
A method for forming an organic light-emitting display device, comprising the steps of:
- depositing a thin-film transistor switch circuit having an output on a substrate;
- depositing an electrode layer of light transmissive conductive organic material comprising a sheet resistance of less than 1000 Ohm/square in electrical contact with the output of the thin-film transistor circuit;
- and
- depositing an organic light-emitting layer over the electrode layer.
