Organic EL element and light-emitting apparatus including the same

1. An organic EL element comprising:

a first electrode having a light-transmission property;

a functional layer which is located on the first electrode and which includes a light-emitting layer; and

a second electrode which is located on the functional layer, the second electrode having an opening which exposes a part of the functional layer, the second electrode including a scatter reflection surface which scatters and reflects a light emitted from the light-emitting layer, the scatter refection surface opposing to the functional layer,

wherein the second electrode contains a plurality of particles which compose the scatter reflection surface, and

the plurality of particles contain spherical particles and flake-shaped particles, the spherical particles being contained more than the flake-shaped particles in terms of mass ratio.

2. The organic EL element according to claim 1 , wherein an arithmetic mean particle diameter of the plurality of particles is 0.1 μm or more and 10 μm or less.

3. The organic EL element according to claim 1 , wherein an interface between the second electrode and the functional layer has an uneven shape.

4. The organic EL element according to claim 1 , wherein an interface between the second electrode and the functional layer has a convex shape protruding toward the functional layer side.

5. The organic EL element according to claim 1 ,

wherein the second electrode is configured such that a light incident from outside transmits through the openings in the second electrode and such that the light emitted from the light-emitting layer is emitted substantially from a first electrode side.

6. A light-emitting apparatus comprising:

the organic EL element according to claim 1 , and

a drive circuit which supplies an electric power to the organic EL element.
