Abstract
A light-emitting device includes a first light-emitting element emitting a first light with a first dominant wavelength including a first MQW structure including a first number of MQW pairs; a second MQW structure on the first MQW structure, including a second number of MQW pairs; and a tunneling layer between the first MQW structure and the second MQW structure; and a second light-emitting element emitting a third light with a third dominant wavelength, wherein the first number is different from the second number.
Claims20
A light-emitting device, comprising:
- a first light-emitting element, comprising:
- a first MQW structure configured to emit a first light with a first dominant wavelength;
- a second MQW structure configured to emit a second light with a second dominant wavelength on the first MQW structure;
- and
- a carrier carrying the first light-emitting element;
- wherein a difference between the first dominant wavelength and the second dominant wavelength is 5 nm to 30 nm.
