摘要：
A light emitter and a method of manufacturing a light emitter. The light emitter includes a first electrode, a charge injection transport layer, a light-emitting layer, and a second electrode that are layered in this order. At least the light-emitting layer is defined by a bank that has at least one liquid-repellent surface. The charge injection transport layer is principally composed of a metal compound that is more liquid-philic than the surface of the bank. The charge injection transport layer includes 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.
