ORGANIC LIGHT-EMITTING DEVICE AND ORGANIC DISPLAY DEVICE EACH INCLUDING LIGHT EMITTERS IN A TWO-DIMENSIONAL ARRANGEMENT ALONG A MAIN SURFACE OF A SUBSTRATE, THE LIGHT EMITTERS BEING DEFINED BY BANKS

摘要

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.

主权项

1. An organic light-emitting device comprising:
a substrate; light emitters in a two-dimensional arrangement along a surface of the substrate; and banks that define the light emitters, wherein each of the light emitters comprises: a first electrode disposed above the substrate; an organic functional layer disposed above the first electrode, the organic functional layer including at least an organic light-emitting layer; and a second electrode disposed on the organic functional layer, wherein the banks comprise: first banks that are each elongated in a first direction along the surface of the substrate and are arranged to be separated from each other in a second direction along the surface of the substrate that is perpendicular to the first direction; and second banks that are each elongated in the second direction and are arranged to be separated from each other in the first direction, wherein the first banks and the second banks each comprise an insulating material, at least a surface portion of each of the first banks that faces the organic functional layer contains fluorine, at least a surface portion of each of the second banks that faces the organic functional layer contains fluorine, the first banks are above the second banks at each intersection between the first banks and the second banks, and fluorine concentration of the surface portion of each of the second banks is less than 10% of fluorine concentration of the surface portion of each of the first banks.
