ABSTRACT:
To provide a method of improving an efficiency for extracting light in a self light-emitting device using an organic EL material. In the self light-emitting device having a structure in which an EL layer (102) is sandwiched between a transparent electrode (103) and a cathode (101), a film thickness of the EL layer (102) and a film thickness of the transparent electrode (102) are equivalent to the film thicknesses in which there is no occurrence of a guided light, and an inert gas is filled in a space between the transparent electrode (103) and a cover material (105).
