Abstract:
1. A double-sided light-emitter that emits light from both sides thereof, comprising: a first electrode; a charge injection transport layer; a functional layer including a light-emitting layer; and a second electrode, the first electrode, the charge injection transport layer, the functional layer and the second electrode being layered in this order, at least the light-emitting layer being defined by a bank, wherein the first electrode and the second electrode are transparent electrodes, at least a surface of the bank is liquid-repellent, and the charge injection transport layer is composed of a metal compound that is more liquid-philic than the surface of the bank, the charge injection transport layer has a recessed structure so that in a region defined by the bank, the charge injection transport layer is lower than a bottom surface of the bank, the recessed structure of the charge injection transport layer includes: the inner bottom portion has a smaller film thickness than the inner side portion.
