A light emitting device includes a first light emitting element which includes a first MQW structure including a first number of MQW pairs, a second MQW structure including a second number of MQW pairs on the first MQW structure, and a tunnel ring layer which is arranged between the first MQW structure and the second MQW structure, and emits first light with a first dominant wavelength; and a second light emitting element which emits third light with a third dominant wavelength. The first number is different from the second number. |
