Abstract: An individual hole transport layer is individually disposed between a common hole transport layer and a light emitting layer in each sub pixel, and the energy level value of the lowest unoccupied molecular orbital of the individual hole transport layer is smaller than the energy level value of the lowest unoccupied molecular orbital of the common hole transport layer, but larger than the energy level value of the lowest unoccupied molecular orbital of the light emitting layer in sub pixel. Thus, a hole can be efficiently injected into the light emitting layer.
