  • Patent number: 8632894
    Abstract: A substrate for an electronic device having high carrier transport ability, a method for manufacturing a substrate for an electronic device which can manufacture such a substrate for an electronic device, an electronic device provided with the substrate for an electronic device and having improved properties, and electronic equipment having high reliability are provided. A substrate for an electronic device includes a light emitting layer (organic semiconductor layer), a cathode (inorganic layer), and an intermediate layer provided between the light emitting layer and the cathode so as to make contact with both of the light emitting layer and the cathode. The intermediate layer is constituted of a compound (1) represented by a general formula R—X—O-M as a main component thereof. In the general formula, the R is a hydrocarbon group, the X is any one of binding groups comprising a single bond, a carbonyl group and a sulfonyl group, and the M is any one of a hydrogen atom and a metal atom.
