Abstract
A light-emitting device includes a light-emitting laminated structure, a first electrode, and a second electrode. The first electrode has a reflection layer, an intermediate layer, and an electrically conductive layer. The intermediate layer includes a barrier layer having a first repeating paired layer unit and a second repeating paired layer unit, each of which has a platinum layer. The first repeating paired layer unit is closer to the electrically conductive layer than the second repeating paired layer unit, and a thickness of the platinum layer of the first repeating paired layer unit is greater than a thickness of the platinum layer of the second repeating paired layer unit.
