Abstract:
1. A method for manufacturing an organic EL display device comprising: preparing an organic EL light emitting device comprising at least a first electrode, an organic EL layer, and a second electrode that are disposed over a first substrate; preparing a color conversion filter comprising at least a color conversion filter layer that is disposed over a second substrate; placing the organic EL light emitting device and the color conversion filter in an environment in which concentrations of water and oxygen are controlled; applying a peripheral sealing agent with a ring shape around the color conversion filter; applying a filler material over the color conversion filter layer and inside the peripheral sealing agent; transferring the organic EL light emitting device and the color conversion filter into a vacuum chamber and evacuating the vacuum chamber; carrying out a preliminary alignment of the organic EL light emitting device and the color conversion filter and bonding the organic EL light emitting device and the color conversion filter to obtain an aggregate; taking out the aggregate to an environment in which concentrations of water and oxygen are controlled and pressure is at atmospheric pressure; and irradiating ultraviolet radiation to the aggregate for curing the peripheral sealing agent in the environment in which concentrations of water and oxygen are controlled and pressure is at atmospheric pressure to obtain an organic EL display device.
