Light emitting device, electronic device, and method of manufacturing light emitting device

A method of manufacturing a light emitting device having at least one pixel having a light emitting element, the method comprising:

• a partition-wall forming step of forming a plurality of first partition walls in such a way as to extend in a first direction over a substrate and partition a luminous-layer forming region where a luminous layer of the light emitting element is to be formed, and at least one second partition wall in such a way as to extend in a second direction orthogonal to the first direction and connect end portions of the plurality of first partition walls;
• and
• a lyophobic-degree adjusting step of adjusting lyophobic degrees of the first partition walls and the second partition wall such that the lyophobic degree of the second partition wall becomes lower than that of a center region between both ends of each of the first partition walls in the first direction;
• wherein the lyophobic-degree adjusting step includes a first plasma irradiation step and a second plasma irradiation step;
• wherein the first plasma irradiation step includes a step of irradiating oxygen plasma onto a surface of the substrate, each of the first partition walls, and the second partition wall to lyophilize the surface of the substrate, each of the first partition walls, and the second partition wall;
• and
• wherein the second plasma irradiation step includes a step of moving a spot type plasma irradiation unit, which locally discharges a plasma jet, along a region including at least the center region of each of the first partition walls while discharging the plasma jet containing CF4 plasma from the spot type plasma irradiation unit, thereby irradiating the CF4 plasma selectively onto the region including at least the center region of each of the first partition walls to vest the region including at least the center region of each of the first partition walls with a lyophobic property.
