Abstract
An organic light-emitting device including a substrate, light emitters in a two-dimensional arrangement along a surface of the substrate, and banks that define the light emitters. The banks include elongated first banks and elongated second banks. The first banks and the second banks intersect. The first banks and the second banks include insulating material, and surfaces of the first banks and the second banks that face an organic functional layer of any of the light emitters contain fluorine. The first banks are above the second banks at each intersection between the first banks and the second banks. Fluorine concentration of the surface portion of each of the second banks is less than fluorine concentration of the surface portion of each of the first banks.
