Abstract:
1. An organic EL display device comprising: a pixel electrode; a first light emission layer which includes a first dopant material having a first absorbance peak in absorbance spectrum characteristics in an optical quenching state and a first host material having a second absorbance peak on a shorter wavelength side than the first absorbance peak, the first light emission layer being disposed above the pixel electrode; a second light emission layer which includes a second dopant material having a third absorbance peak in absorbance spectrum characteristics and a second host material having a fourth absorbance peak on a shorter wavelength side than the first absorbance peak and than the third absorbance peak, the second light emission layer being disposed above the first light emission layer; a third light emission layer which includes a third dopant material and a third host material, the third light emission layer being disposed above the second light emission layer; and a counter-electrode which is disposed above the third light emission layer, wherein the first host material and the second host material have an absorbance of 10% or less at wavelengths of 350 nm or more in normalized absorbance spectrum characteristics thereof.
