Abstract
Embodiments described herein relate to a device including a substrate, a plurality of adjacent pixel-defining layer (PDL) structures disposed over the substrate, and a plurality of sub-pixels. Each sub-pixel includes adjacent first overhangs, adjacent second overhangs, an anode, a hole injection layer (HIL) material, an additional organic light emitting diode (OLED) material, and a cathode. Each first overhang is defined by a body structure disposed on and extending laterally past a base structure disposed on the PDL structure. Each second overhang is defined by a top structure disposed on and extending laterally past the body structure. The HIL material is disposed over and in contact with the anode and disposed under the adjacent first overhangs. The additional OLED material is disposed on the HIL material and extends under the first overhang.
