Abstract:
1. A method for fabricating a display device, comprising: forming an underlying layer on a substrate; forming an insulating layer on the underlying layer to extend in a range at or between 100 nm and 500 nm from a top of the underlying layer while exposing a portion of the underlying layer to form a channel, the formed insulating layer having an opposing edge tapering into the exposed portion of the underlying layer to form a boundary of the channel; and forming an organic electroluminescent layer on the exposed portion of the underlying layer and over the edge of the insulating layer so as to contact the underlying layer and the insulating layer by a Laser Induced Thermal Imaging (LITI) method, so that the organic electroluminescent layer is entirely within the channel, the edge of the insulating layer intrudes between the organic electroluminescent layer and the underlying layer, and an end of the organic electroluminescent layer on the edge of the insulating layer is separated from the underlying layer by the edge of the insulating layer; wherein the insulating layer is less than 200 nm thick.
