ABSTRACT:
A first layer having a refractive index higher than that of a light transparent substrate is formed on the light transparent substrate, and a second layer having a refractive index higher than that of the first layer is formed on the first layer, and an electrode layer having a refractive index higher than that of the second layer is formed on the second layer in accordance with the present invention. By means of this configuration, a spherical-wave-shaped wavefront emitted from a point light source of an emission layer of a light-emitting device to all directions, is converted to a plane-wave-shaped wavefront within the substrate, which allows the light to be effectively emitted outside the substrate, so that a light-emitting device substrate having good light extraction efficiency and a light-emitting device using the same may be provided.
