Abstract:
1. A method of manufacturing an organic EL device, comprising: forming a first pixel electrode, a second pixel electrode, and a third pixel electrode on an insulative substrate; forming a hole transport layer of a material having an absorbance bottom, commonly above the first to third pixel electrodes; forming a first light emission layer which includes a first dopant material having a first absorbance peak in absorbance spectrum characteristics of the first dopant material, above the hole transport layer and commonly above the first to third pixel electrodes; exposing a region of the first light emission layer which is above the second pixel electrode and the third pixel electrode to optically quench the first dopant material in the region; forming a second light emission layer which includes a second dopant material having a second absorbance peak in absorbance spectrum characteristics of the second dopant material, above the first light emission layer and commonly above the first to third pixel electrodes; exposing a region of the second light emission layer which is disposed above the third pixel electrode to optically quench the second dopant material in the region; forming a third light emission layer which includes a third dopant material, above the second light emission layer and commonly above the first to third pixel electrodes; and forming a counter-electrode above the third light emission layer.
