ABSTRACT:
In a stacked display device with light-emitting units composed of organic layers and stacked together, the use of a stable material in at least a portion of a charge generation layer makes it possible to achieve improvements in environmental stability and also to attain an improvement in the efficiency of injection of charges from the charge generation layer into the light-emitting units. The display device can be readily fabricated. In a display device (11) provided with a plurality of light-emitting units (14-1)(14-2), each of which includes at least an organic light-emitting layer (14c), stacked together between a cathode (16) and an anode (13), and also with a charge generation layer (15) held between the respective light-emitting units (14-1)(14-2), at least a portion of the charge generation layer (15) is composed of an oxide or fluoride which contains at least one of alkali metals and alkaline earth metals.
