ABSTRACT:
An organic EL display device includes a first light emission layer which includes a first dopant material having a first absorbance peak in absorbance spectrum characteristics and a first host material having a first absorbance bottom on a shorter wavelength side than the first absorbance peak, the first light emission layer extending over the first to third organic EL elements and being disposed above pixel electrodes of the first to third organic EL elements, and a second light emission layer which includes a second dopant material having a second absorbance peak in absorbance spectrum characteristics and a second host material having a second absorbance bottom on a shorter wavelength side than the first absorbance peak and than the second absorbance peak, the second light emission layer extending over the first to third organic EL elements and being disposed above the first light emission layer.
