More Information
Summary:A light-emitting device comprises sequentially in a stacking order a supporting substrate, a metal reflecting layer, a transparent conductive non-oxide layer, a transparent conductive oxide layer, a first conductivity-type semiconductor layer, a semiconductor active structure and a second conductivity-type semiconductor layer. The first conductivity-type semiconductor layer has a first work function. The metal reflecting layer has a second work function. The transparent conductive oxide layer has a third work function smaller than the first work function. The transparent conductive non-oxide layer has a fourth work function smaller than the first work function wherein a difference between the third work function and the fourth work function is smaller than 0.5 eV.
