Abstract
A light emitting device includes: a substrate; a first electrode and a second electrode on the substrate and spaced apart from each other; a light emitting diode between the first electrode and the second electrode and connected to the first and second electrodes; a first contact on the first electrode; and a second contact on the second electrode. The first contact contacts the first electrode and a first portion of the light emitting diode, and the second contact contacts the second electrode and a second portion of the light emitting diode.
Claims15
A light emitting device comprising:
- a substrate;
- a first electrode and a second electrode on the substrate and spaced apart from each other;
- a light emitting diode between the first electrode and the second electrode, the light emitting diode being connected to the first electrode and the second electrode;
- a first contact on the first electrode, the first contact contacting the first electrode and a first portion of the light emitting diode;
- and
- a second contact on the second electrode, the second contact contacting the second electrode and a second portion of the light emitting diode.
A method of manufacturing a light emitting device, the method comprising:
- coating a plurality of light emitting diodes on a first electrode and a second electrode, the first and second electrodes being spaced apart from each other on a substrate;
- aligning the plurality of light emitting diodes between the first electrode and the second electrode by forming an electric field between the first electrode and the second electrode;
- forming a first contact layer covering the first electrode, the second electrode, and the plurality of light emitting diodes;
- forming a first contact contacting the first electrode and a first portion of the light emitting diode by etching the first contact layer using a mask;
- and
- forming a second contact contacting the second electrode and a second portion of the light emitting diode.
