Abstract:
A display device includes: a plurality of pixel electrodes; a first carrier injection layer, a first carrier transport layer, a light-emitting layer, a second carrier transport layer, and a second carrier injection layer provided in order on the plurality of pixel electrodes; and a counter electrode provided on the second carrier injection layer. The second carrier has a polarity opposite to that of the first carrier. The counter electrode is connected to one layer of the first carrier transport layer and the first carrier injection layer, penetrating a layer situated between the one layer and the counter electrode, between the pixel electrodes adjacent to each other in a plan view. Alternatively, an upper surface of an intermediate electrode situated between the pixel electrodes adjacent to each other in a plan view is connected to the first carrier injection layer.
