AbstractThere is provided a substrate for a light emitting device which includes an electrically conductive and transparent film which is in contact with a surface of a low refractive index member of which refractive index is greater than 1 and not greater than 1.30. With such light emitting device, a ratio of light which is withdrawn outside through the low refractive index member is increased, so that a coupling-out efficiency for surface emission of light withdrawn into the ambient air is increased.
