Abstract
A light-emitting structure includes a substrate, a sub-pixel stack over a surface of the substrate, and a bank including a first bank portion and a second bank portion. The sub-pixel stack has an emissive stack including an emissive layer between a first transport layer and a second transport layer, a first electrode layer coupled to the first transport layer, and a second electrode layer coupled to the second transport layer. The second bank portion is between the first bank portion and the sub-pixel stack, and the bank surrounding at least the emissive stack and the first electrode layer forms an interior space above the sub-pixel stack.
