Abstract
An organic light-emitting element including: a substrate; a light-emitting part above the substrate, the light-emitting part including an organic layer; and banks defining bounds of the organic layer in a direction along a main surface of the substrate. In the organic light-emitting element, in plan view, a surface of the organic layer is longer in a first direction than in a second direction perpendicular to the first direction, and in the second direction, the surface of the organic layer is convex, protruding upwards in a thickness direction of the organic layer, and in the first direction, the surface of the organic layer is concave, protruding downwards in the thickness direction.

- in plan view, a surface of the organic layer is longer in a first direction than in a second direction perpendicular to the first direction, and
- in the second direction, the surface of the organic layer is convex, protruding upwards in a thickness direction of the organic layer, and in the first direction, the surface of the organic layer is concave, protruding downwards in the thickness direction.
An application-type device comprising:
- a substrate provided with a recess;
- and
- a functional layer, ink applied with respect to the recess and then dried forming the functional layer, wherein
- in plan view, a surface of the functional layer is longer in a first direction than in a second direction perpendicular to the first direction, and
- in the second direction, the surface of the functional layer is convex, protruding upwards in a thickness direction of the functional layer, and in the first direction, the surface of the functional layer is concave, protruding downwards in the thickness direction.
A method of manufacturing an organic light-emitting element, comprising:
- preparing a substrate;
- forming banks above the substrate to surround a part of an area above the substrate;
- applying ink containing organic material to fill a recess formed by the banks surrounding the part of the area above the substrate, and forming a layer of applied ink;
- and
- drying the layer of applied ink and forming an organic layer, the organic layer included in a light-emitting part of the organic light-emitting element, wherein
- in plan view, a surface of the organic layer, which is formed inside the recess, is longer in a first direction than in a second direction perpendicular to the first direction, and
- in the second direction, the surface of the organic layer is convex, protruding upwards in a thickness direction of the organic layer, and in the first direction, the surface of the organic layer is concave, protruding downwards in the thickness direction.
A method of manufacturing an application-type device, the method comprising:
- preparing a substrate provided with a recess;
- applying ink with respect to the recess;
- and
- drying the ink and forming a functional layer, wherein
- in plan view, a surface of the functional layer, which is formed inside the recess, is longer in a first direction than in a second direction perpendicular to the first direction, and
- in the second direction, the surface of the functional layer is convex, protruding upwards in a thickness direction of the functional layer, and in the first direction, the surface of the functional layer is concave, protruding downwards in the thickness direction.
