Display device and electronic device

摘要

It is an object of the present invention to provide a display device without using an oxide light-transmitting conductive film which is necessary in a conventional method. In addition, it is another object of the present invention to provide an electronic device having a display device using a new electrode material. It is a summary of the present invention to form an electrode of a pixel or a pixel portion with a light-transmitting conductive film containing a hole-transporting organic compound and a metal oxide which shows an electron accepting property with respect to the hole-transporting organic compound. The hole-transporting organic compound and the metal oxide which shows an electron accepting property with respect to the hole-transporting organic compound are composed to have resistivity of less than or equal to 1×106 Ω·cm, thereby being able to serve as an electrode of a pixel. It is not necessary to form a transparent electrode using a particular premium grade material; therefore, the manufacture cost of an electronic device typified by a flat panel display can be reduced.

主权项

1. A device comprising:
a partition layer directly over and in contact with an insulating surface, the partition layer has an opening portion in which part of the insulating surface is exposed; an anode of a pixel comprising a light-transmitting conductive film, wherein the anode is directly over and in contact with a part of the partition layer and directly over and in contact with the part of the insulating surface; and an electroluminescence layer directly over and in contact with the anode, wherein an edge portion of the anode is covered by and directly in contact with the electroluminescence layer, wherein the light-transmitting conductive film contains a hole-transporting organic compound and molybdenum oxide which shows electron acceptability with respect to the hole-transporting organic compound, wherein the electroluminescence layer comprises at least a light-emitting layer, and wherein the hole-transporting organic compound and the molybdenum oxide are in a mixed state in the light-transmitting conductive film.
