Abstract

This invention addresses the problem of providing a charge-transporting thin film with small variations in properties due to disturbance and small variations in resistance over time during application of current. The invention further provides a charge-transporting thin film with a secondary effect of small variations over time and stable luminescent properties. The charge-transporting thin film of the present invention contains one or more types of functional organic compounds having chiral elements, and is characterized in that the total of the number of chiral elements per molecule in each type of the functional organic compounds summed over all types of the functional organic compounds is four or more.
