<P>PROBLEM TO BE SOLVED: To provide a display device having a good luminous characteristic and enabling easy and stable manufacture. <P>SOLUTION: The display device includes organic light-emitting devices each having an organic compound layer including a first light-emitting layer and a second light-emitting layer common to at least each organic light-emitting device. The layer constituting the organic compound layer has an identical film thickness throughout the entire organic light-emitting devices. The first light-emitting layer includes a first light-emitting dopant and a second light-emitting dopant mutually different in luminous color, emission spectrum and light-emitting position in the film thickness direction. The second light-emitting layer includes a third light-emitting dopant different from the first light-emitting dopant and the second light-emitting dopant in a luminous color and an emission spectrum. In at least two dopant types, a distance between the first electrode and the light-emitting position in the film thickness direction satisfies a condition of mutually strengthening light in optical interference. <P>COPYRIGHT: (C)2013,JPO&INPIT |
