Organic electroluminescent display device and production method thereof

An organic electroluminescent display device comprising an electroluminescent element,

• the electroluminescent element comprising a lower electrode, an organic layer, a light-emitting layer, and an upper electrode, stacked one above the other on and above a substrate in this order, wherein
• the organic electroluminescent display device further includes a bank arranged on the organic layer;
• the organic layer is a charge injecting/transporting layer;
• the organic electroluminescent display device further includes an intermediate layer arranged to block a carrier transferred from the upper electrode between the charge injecting/transporting layer and the light-emitting layer;
• and
• the bank is arranged on and above the intermediate layer.
