Abstract
A light emitting device includes a cathode, an anode, a light emitting layer provided between the cathode and the anode, an intermediate layer provided between the cathode and the light emitting layer so as to be in contact with both the cathode and the light emitting layer. The intermediate layer includes a base in the form of a layer, the base being constituted of a metal oxide based semiconductor material as a main component thereof and having a first surface which is in contact with the light emitting layer and a second surface opposite to the first surface, and a dye carried on the first surface of the base and inner surfaces of pores formed in the base so as to be in contact with the light emitting layer. By using the light emitting device mentioned above, it is possible to improve properties of the light emitting device such as luminous efficiency and the like. A method for manufacturing such a light emitting device is also provided. An electronic device provided with such a light emitting device is also provided. Electronic equipment provided with such an electronic device is also provided.
