To manufacture display devices with improved image quality and reliability or display devices with a large screen at low cost with high productivity. An electrode layer containing a conductive polymer is used as an electrode layer of a display element in a display device and an inorganic insulating film serving as a passivation film is provided between the electrode layer and a display layer. Ionic impurities in the electrode layer are easily ionized and become mobile ions and thereby deteriorating a liquid crystal material or the like which is included in a display layer in a display element. Ionic impurities in the electrode layer are prevented from moving into a display layer by the inorganic insulating film. Thus, the reliability of the display device can be improved. |
