ORGANIC SEMICONDUCTOR LIGHT EMITTING ELEMENT, DISPLAY DEVICE USING SAME, AND METHOD FOR MANUFACTURING ORGANIC SEMICONDUCTOR LIGHT EMITTING ELEMENT

摘要

An organic semiconductor light emitting element wherein light emitting efficiency is effectively improved. The organic semiconductor light emitting element is provided with an electron injecting electrode (3) and a hole injecting electrode (4) arranged at an interval; an organic semiconductor section (5) arranged in an interelectrode region (10) between the electrodes; a silicon oxide film (2); and a gate electrode (1) facing the interelectrode region (10) having the silicon oxide film in between. The organic semiconductor section (5) is provided with a P-type organic semiconductor material layer (7) and an N-type organic semiconductor material layer (6), which have a PN junction region (12) substantially in an intermediate section (11) of the interelectrode region (10); and an organic light emitting material layer (8) arranged in the PN junction region (12).
