Abstract: A light-emitting device includes at least one light-emitting region. The at least one light-emitting region includes: a lower electrode in plan view; an upper electrode provided across from at least one lower electrode including the lower electrode; and a plurality of functional layers stacked on top of another between the lower electrode and the upper electrode. The plurality of functional layers include at least: a light-emitting layer provided between the lower electrode and the upper electrode; and a first functional layer provided between the lower electrode and the light-emitting layer, and adjacent to the light-emitting layer. The light-emitting layer contains quantum dots, ligands, and a photo-crosslinking agent. The first functional layer contains a photocurable resin. An end face of the light-emitting layer and an end face of the first functional layer are flush with each other.

Abstract: A top-emitting pixel device is disclosed. The pixel device may include a reflective bottom electrode disposed over a substrate, a first charge transport layer disposed over the reflective bottom electrode, an emissive layer disposed over the first charge transport layer, and a second charge transport layer disposed over the emissive layer.
