Abstract
A light emitting device comprises: a substrate; a first electrode on the substrate, the first electrode having holes, and having inclined surfaces along the peripheries of the holes; second electrodes on the substrate, each of which is in a respective one of the holes of the first electrode; and light emitting elements between the first electrode and the second electrodes, the light-emitting elements being electrically connected to the first electrode and the second electrodes.
Claims20
A light-emitting device comprising:
- a substrate;
- a first electrode on the substrate, the first electrode comprising holes, and having inclined surfaces along peripheries of the holes;
- second electrodes on the substrate, each of which is in a respective one of the holes of the first electrode;
- and
- light-emitting elements between the first electrode and the second electrodes, the light-emitting elements being electrically connected to the first electrode and the second electrodes.
A method of manufacturing a light-emitting device, the method comprising:
- forming an electrode layer on a substrate;
- patterning the electrode layer and forming first pixel electrodes arranged independently of each other and unseparated electrode patterns surrounding the first pixel electrodes;
- arranging light-emitting elements on the unseparated electrode patterns and the first pixel electrodes;
- forming an electric field between the unseparated electrode patterns and the first pixel electrodes and aligning the light-emitting elements;
- and
- patterning the unseparated electrode patterns and forming a second pixel electrode surrounding at least one of the first pixel electrodes.
