ORGANIC LIGHT-EMITTING TRANSISTOR AND DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an organic light-emitting transistor capable of improving luminous power conversion efficiency while controlling a voltage of an organic light-emitting layer, and a display device. SOLUTION: The organic light-emitting transistor has a drain electrode layer opposed to a source electrode layer and the organic light-emitting layer formed between the source electrode layer and the drain electrode layer. The organic light-emitting transistor has a semiconductor layer formed between the organic light-emitting layer and the source electrode layer and a gate electrode layer arranged through a gate insulating film on the reverse side to a surface opposed to the drain electrode layer in the source electrode layer. The organic light-emitting transistor further has a charge control layer formed and opened between the organic light-emitting layer and the source electrode layer and a relay region formed between the charge control layer and the source electrode layer and relaying charges from the source electrode layer to the opening.
