Light emitting device with light emiiting element disposed above color filter
In one example, a light emitting device comprises a substrate, a color filter disposed above the substrate, and a light emitting element disposed above the color filter. The light emitting element includes a first electrode, an organic layer and a second electrode. The first electrode has a recessed shape or a domed shape in a cross-sectional view, and the second electrode is disposed between the color filter and the first electrode. The light emitting element is configured to emit a light towards the substrate. A first layer is 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.
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 having a recessed shape or a domed shape in a cross-sectional view,
the second electrode being disposed between the color filter and the first electrode, 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.
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 an upper surface of the second layer.
5 . The light emitting device according to claim 4 , wherein the first layer and the second layer combine to form a 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.
7 . The light emitting device according to claim 1 , wherein the light emitting device is a bottom type light emitting device.
