Disclosed is an organic thin film transistor, which is provided with at least three terminals of a gate electrode, a source electrode, and a drain electrode, an insulating layer, and an organic semiconductor layer, on a substrate and controls an electric current between the source-drain electrodes by applying a voltage to the gate electrode. The organic semiconductor layer comprises a specific organic compound having an aromatic hydrocarbon group or a heteroaromatic ring group and an acetylene structure at the center. The organic thin film transistor emits light by making use of an electric current flowing between the source-drain electrodes and controls the emitting light by applying a voltage to the gate electrode. Further, a chemical compound suitable for the organic thin film transistor is disclosed. |
