ELECTRONIC ELEMENT EMPLOYING HYBRID ELECTRODE HAVING HIGH WORK FUNCTION AND CONDUCTIVITY

摘要

An electronic element is provided. The electronic element may include a hybrid electrode having a high work function and conductivity which has a conductivity of at least 1 S/cm and includes: a work function-tuning layer; and a conductivity-tuning layer which is in contact with the first surface of the work function-tuning layer. Accordingly, the electronic element which employs the hybrid electrode having a high work function and conductivity may have excellent light-emitting efficiency and/or photoelectric conversion efficiency even if a hole injection layer for work function adjustment is omitted.
