ABSTRACT:
An OLED device having pillars with a cross section that is wider on the top. The pillars structure a conductive layer during deposition into distinct portions located between the pillars and on the top of the pillars. In one embodiment, the grooves between the pillars extend outside the electrode region to prevent shorting of adjacent electrodes.
