| 摘要 |
A luminescent device which is excellent in transparency, heat resistance, passivation (gas barrier, oligomer discharge prevention, or outgas reduction) water (humidity) absorption resistance, chemical deterioration stability, dimension form stability, surface antireflection electric insulation, infrared deterioration resistance, and weatherability which has a substrate and a protective member so excellent in productivity such as of the feasibility of film formation under the normal pressure, and which can be manufactured highly reliably and easily at a low cost. The luminescent device comprises a substrate (1) having flexibility, transparency and heat resistance, a lower electrode (4), a luminescent layer (4) and an upper electrode (4) the three formed over the substrate (1) and having transparency and a silica film and/or a silica-based film (3) made by applying polysilazane at least to the substrate side or on both the substrate side and the opposite side, when viewed from the luminescent layer (4), and oxidizing the polysilazane.
