    • In conventional organic EL light-emitting devices, the ITO used for a transparent electrode has a refractive index of about 2.0 larger than the refractive index of 1.5 of a transparent glass substrate. As a result, the mode of most of light traveling from the transparent electrode toward the glass substrate is the transparent electrode guided mode, and no light is emitted from the transparent electrode toward the glass substrate. According to the invention, the light extraction efficiency of conventional light-emitting devices such as organic EL light-emitting devices is improved by using mode conversion means so as to solve the problem that conventional light-emitting devices such as organic EL light-emitting devices have low light extraction efficiencies. A light-emitting device of the invention comprises a light-emitting layer on a substrate and mode conversion means for converting the mode from the guided mode into an emission mode. The mode conversion means is provided in the substrate, in the light-emitting layer, or at the interface between the substrate and the light-emitting layer.
    • 在传统的有机EL发光器件中,用于透明电极的ITO具有比透明玻璃衬底的折射率1.5大约2.0的折射率。 结果,从透明电极朝向玻璃基板行进的大部分光的模式是透明电极引导模式,并且没有光从透明电极朝向玻璃基板发射。 根据本发明,通过使用模式转换装置来提高诸如有机EL发光器件的常规发光装置的光提取效率,以解决诸如有机EL发光装置之类​​的常规发光装置的问题 具有低光提取效率。 本发明的发光装置包括在基板上的发光层和用于将模式从导模转换为发射模式的模式转换装置。 模式转换装置设置在基板,发光层中或基板与发光层之间的界面处。
