ABSTRACT:
To provide a composition in which the viscosity is hardly changed with the passage of time and an organic conductive layer including the composition in order to planarize the surface of a layer formed by an inkjet process and in order to stabilize the properties, a composition contains an organic conductive material and at least one solvent, wherein the changing rate of the viscosity thereof is within a range of ±5% when 30 days have passed after the preparation. The solvent preferably contains a glycol medium. An organic conductive layer includes the composition having the above configuration.
