Abstract
A light-emitting device, which has a structure that improves an opening ratio and light extraction efficiency, can solve a problem of an etching residue occurred during forming the device itself, and reduce deterioration due to poor coverage and short-circuiting to improve greatly the reliability, and a method for manufacturing the light-emitting device. In the light-emitting device having a structure that improves light extraction efficiency, a material used for forming a first electrode is Ti/TiN/Al (or Al—Ti)/Ti (or TiN).
