Abstract

A top emitting quantum dot light emitting diode (QLED) apparatus for an emissive display apparatus sub-pixel, with at least one bank defining an emissive region of the emissive display apparatus sub-pixel, includes an emissive layer deposited in the emissive region between a first electrode and a second electrode. The first electrode includes a reflective metal, and the second electrode has a transparent conductive electrode and an auxiliary electrode. The bank has a sloped portion adjacent the emissive region. The auxiliary electrode includes a reflective conductive metal and is configured to cover the sloped portion, and the sloped portion is configured at an angle, such that the auxiliary electrode reflects internally reflected light out of the sub-pixel in a viewing direction, and the auxiliary electrode is configured with a partially light scattering surface to broaden a reflective angle range of the auxiliary electrode.
