ABSTRACT:
It is a problem to provide an electric apparatus less in consumption power and long in life by the manufacture using the display device. An insulating bank is provided in a form surrounding the pixel portions on first electrodes over a substrate. The entire surface is applied, by a wet scheme (method), with an organic conductive film which has a thickness form of T2>T1>T3under the influence of the insulating bank. Accordingly, the portion T3has an increased resistance in a lateral direction, making possible to prevent against crosstalk. Due to a conductive polymer as a buffer layer, a display device can be provided which is low in drive voltage. Furthermore, because the portion T2is increased in thickness, the electric-field concentration is relaxed at and around the pixel portion. This makes it possible to prevent the organic light-emitting element from deteriorating at around the pixel.
