Abstract
Description
図3および図4を参照すると、単一基板50上に複数個の発光セル57が位置する。前記基板50は、絶縁または導電性基板であってもよい。
図5を参照すると、基板50上に、第1の導電型半導体層54、活性層56、および第2の導電型半導体層60を形成する。また、前記第1の導電型半導体層54を形成する前、前記基板50上にバッファ層52を形成してもよい。
図8は、本発明の他の実施例による交流駆動型発光ダイオードを説明するための平面図である。
一方、配線78が、n型電極64上において互いに連結される場合、配線68の接着力が改善され得るが、互いに分離されてもよい。
図9を参照すると、本実施例による交流駆動型発光ダイオードは、図3を参照して説明した交流駆動型発光ダイオードと略同一の構成要素を有する。但し、透明電極構造体82が、図3の透明電極構造体62と異なり、これにより、配線88が図3の配線68と異なる。以下、前記差異点について説明する。
