In the organic thin film transistor in which at least three terminals of a gate electrode, a source electrode and a drain electrode, an insulator layer, and an organic semiconductor layer are provided on a substrate, and a source-drain current is controlled by applying a voltage to the gate electrode. In the organic thin film transistor and organic thin film transistor in which the semiconductor layer includes a specific organic compound having an aromatic hydrocarbon group or aromatic heterocyclic group and an acetylene structure at the center, light emission is obtained by using a current flowing between the source and the drain. Organic thin-film light-emitting transistor that controls light emission by applying voltage to gate electrode, organic thin-film transistor having high response speed and high on / off ratio by using compound suitable for the same, and organic thin-film light-emitting transistor using the same And compounds suitable therefor. |
