    • The light-emitting device includes: a substrate which has a single layer structure in which a conductive member is partially provided on a surface of the substrate; a plurality of light-emitting elements which are directly provided on the surface of the substrate so as to be electrically connected with the conductive member; a first light reflection resin layer; a second light reflection resin layer which is provided in a looped shape on the surface of the substrate so as to surround an area in which the plurality of light-emitting elements are provided; and a sealing resin which covers the plurality of light-emitting elements. In the area in which the plurality of light-emitting elements are provided, the conductive member is covered with the first light reflection resin layer, the conductive member, which is provided under the second light reflection resin layer, is covered with the second light reflection resin layer directly, and a printed resistor, which is provided under the second light reflection resin layer, is covered with the second light reflection resin layer via the first light reflection resin layer. This makes it possible to provide the light-emitting device which (i) reduces absorption of light so as to achieve excellent light extraction efficiency, and (ii) is highly reliable.
    • 发光装置包括:具有单层结构的基板,其中导电构件部分地设置在基板的表面上; 多个发光元件,其直接设置在所述基板的表面上以与所述导电构件电连接; 第一光反射树脂层; 第二光反射树脂层,其以环状设置在所述基板的表面上,以围绕设置有所述多个发光元件的区域; 以及覆盖多个发光元件的密封树脂。 在设置有多个发光元件的区域中,导电部件被第一光反射树脂层覆盖,设置在第二光反射树脂层下方的导电部件被第二光反射覆盖 树脂层和设置在第二光反射树脂层下方的印刷电阻器经由第一光反射树脂层被第二光反射树脂层覆盖。 这使得可以提供(i)减少光的吸收以获得优异的光提取效率的发光装置,(ii)高可靠性。
