<p><P>PROBLEM TO BE SOLVED: To aim longer life of an organic EL display device. <P>SOLUTION: The active matrix type organic EL display device comprises a transparent pixel electrode as a positive electrode, a pixel separation membrane arranged between the pixel electrodes and on its outer edge, a transparent electrode arranged on the pixel separation membrane, an organic EL layer arranged on the transparent electrode, and a common electrode as a negative electrode arranged on the organic EL layer. The transparent pixel electrode is made of In oxide or Zn oxide, and the transparent electrode is made of In oxide or Zn oxide. Its resistance rate of the transparent electrode is higher than the resistance rate of the transparent pixel electrode, the transparent electrodes are arranged on a layer between the pixel separation membrane and the transparent pixel electrode, and the organic EL layer, and the transparent electrode covers the whole display region. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
