Light emitting device with light emitting element including recessed or domed shaped electrodes
A light emission element of an embodiment of the present disclosure includes at least: a base; a recessed portion provided at a surface of the base; a first electrode layer formed at least partially along a shape of a top surface of the recessed portion; an organic layer formed on the first electrode layer at least partially along a shape of a top surface of the first electrode layer; a second electrode layer formed on the organic layer along a shape of a top surface of the organic layer; and a planarization layer formed on the second electrode layer, in which light from the organic layer is emitted to an outside via the second electrode layer and the planarization layer.
1. A light emitting device comprising:
a substrate;
a color filter disposed above the substrate;
a light emitting element disposed above the color filter,
the light emitting element including a first electrode, an organic layer and a second electrode,
the first electrode and the second electrode having a recessed shape or a domed shape in a cross-sectional view,
the second electrode being disposed between the first electrode and the substrate, and
the light emitting element being configured to emit a light towards the substrate; and
a first layer disposed between the light emitting element and the substrate, an upper surface of the first layer having the recessed shape or the domed shape in the cross-sectional view, wherein the first layer is configured as at least a part of a lens through which the light passes.
2. The light emitting device according to claim 1 , wherein the first layer is in contact with the second electrode.
3. The light emitting device according to claim 1 , wherein the first layer has a lower surface, the lower surface having another recessed shape or another domed shape opposite to the recessed shape or the domed shape of the upper surface in the cross-sectional view.
4. The light emitting device according to claim 1 , further comprising:
a second layer disposed above the substrate, a lower surface of the first layer being in contact with the second layer.
5. The light emitting device according to claim 4 , wherein the first layer and the second layer combine to form the lens.
6. The light emitting device according to claim 5 , wherein the lens is configured to direct at least part of the light towards the substrate along a vertical axis at a central region of the light emitting element in the cross-sectional view.
