An organic EL element having a first electrode planarized and a manufacturing method therefor are provided. After an ITO film (11) which is the first electrode is formed on a glass substrate (10), a planarization level film (12) is formed and patterned to form a planarization level film (12a). In addition, the ITO film (11) is over-etched to form an ITO film (11a), and an undercut portion (15) is generated. After a planarization film (14) which is an insulating film is applied on the entire surface, the major part of the planarization film (14) and the planarization level film (12a) are removed, thereby causing an insulating film (14a) formed in the undercut portion (15) to remain with the same thickness as the ITO film (11a). |
