Abstract
An OLED device having pillars with 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. The pillars are formed by patterning a single photosensitive material which is inert to the chemicals used to deposit the organic functional layers of the OLED device. By using such pillars, the electrodes can be formed without damaging organic functional layers while achieving high resolution.
