Abstract: The present invention provides an organic EL display device which exhibits a long lifetime. In an organic EL display device which includes pixel electrodes formed on a substrate, an insulation partition wall surrounding the pixel electrodes, an organic EL layer formed on the pixel electrodes, and a common electrode formed on the organic EL layer, the common electrode is formed of a transparent conductive film which is made of metal oxide, and an auxiliary electrode which is made of opaque metal containing Zn or Mg as a main component is arranged above the common electrode and at positions where the auxiliary electrode overlaps with the insulation partition wall. The auxiliary electrode may be arranged below the common electrode instead of being arranged above the common electrode.

Abstract: The present invention aims at the suppression of chromaticity irregularities and brightness irregularities by reflecting a result of an analysis of film forming misalignment of an organic EL layer. For this end, a drive circuit chip 6 is mounted on a lower side of a display panel 4, and a terminal portion 7 for connection with an external device (a host device) is mounted on an end edge of the lower side of a display panel 4. Film forming misalignment vectors (indicated by arrows) of sub pixels at an arbitrary point in a display region 5 fall within a first quadrant and an angle made between the vectors falls within 90°.
