ABSTRACT:
An organic EL light emitting device and a color conversion filter are placed in an environment in which concentrations of water and oxygen are controlled. A peripheral sealing agent with a ring shape is applied around the color conversion filter, and a filler material is applied over the color conversion filter and inside the peripheral sealing agent. The organic EL light emitting device and the color conversion filter are transferred into a vacuum chamber, which is then evacuated. The organic EL light emitting device and the color conversion filter are preliminarily aligned and then bonded to obtain an aggregate. The aggregate is removed to an environment in which concentrations of water and oxygen are controlled and pressure is at atmospheric pressure, and irradiated with ultraviolet radiation to cure the peripheral sealing agent. The method reduces manufacturing costs and prevents inclusion of water in the internal space.
