Abstract
【解決手段】 基板、n型クラッド層、活性層、p型クラッド層が順次に積層されており、p型クラッド層上に電気的及び光学的特性を向上させることができるように伝導性を有する素材で30μm以下の幅を有するサイズのセルを相互に離隔されるように格子状に形成された格子セル層と、p型クラッド層の表面を保護することができるように、少なくともセル間領域をカバーできるようにp型クラッド層上に形成された表面保護層と、表面保護層と格子セル層上に透明伝導性素材で形成された透明伝導性薄膜層とを備えるトップエミット型窒化物系発光素子である。これにより、p型クラッド層とのオーミック接触特性が改善されて優秀な電流−電圧特性を表すだけではなく、高い光透過性を提供し、素子の発光効率を高めることができる。
