Provided is a light emitter in which high-definition light-emitting layer is patterned, and which can be manufactured at low cost. To achieve the aim, the light emitter including a first electrode 2, a charge injection transport layer 4, a light-emitting layer 6, and a second electrode 8 that are layered in this order, and at least the light-emitting layer 6 is defined by a bank 5. the bank 5 is liquid-repellent at least on a surface thereof, and the charge injection transport layer 4 is principally composed of a metal compound that is more liquid-philic than the surface of the bank. Also, the charge injection transport layer 4 has a recessed structure so that in a region defined by the bank 5, the charge injection transport layer 4 is lower than a bottom surface 5a of the bank 5. |
