摘要： A light emitting device includes: a light emitting layer; an n-type contact layer made of a compound provided on the light emitting layer; a composition modulation layer provided on the n-type contact layer; and a transparent electrode provided on the composition modulation layer. The composition modulation layer consists of a plurality of elements which constitute the compound. A composition ratio of one of the plurality of elements is higher in the composition modulation layer than in the compound. Alternatively, the light emitting device includes: a light emitting layer; an n-type contact layer made of a compound provided on the light emitting layer; a metal layer provided on the n-type contact layer; and a transparent electrode provided on the metal layer. The metal layer is made of a metal having a lower work function than the compound.
