A display device and method for manufacturing thereof |
摘要 |
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 103a is provided in a form surrounding the pixel portions 110a on first electrodes 102a over a substrate. The entire surface is applied, by a wet scheme(method), with an organic conductive film 104. The organic conductive film 104 has a thickness form of T2 > T1 > T3 under the influence of the insulating bank 103. Accordingly, the portion T3 has an increased resistance in a lateral direction, making possible to prevent against crosstalk. Due to a conductive polymer as a buffer layer 104, a display device can be provided which is low in drive voltage. Furthermore, because the portion T2 is 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. |
