A thin film transistor composed of at least three terminals consisting of a gate electrode, a source electrode and a drain electrode; an insulator layer and an organic semiconductor layer on a substrate, which controls its electric current flowing between the source and the drain by applying a electric voltage across the gate electrode, wherein the organic semiconductor layer contains a styryl derivative having a styryl structure expressed by C6H5-CH=CH-C6H5, or a distyryl structure expressed by C6H5-CH=CH-C6H4-CH=CH-C6H5 each without molecular weight distribution. An organic thin film light-emitting transistor which achieves a light emission in the organic thin film transistor by utilizing an electric current flowing between the source and the drain, and further controls the light emission by applying a voltage onto the gate electrode. Both transistors have fast response speeds (driving speeds), and further, achieve large On/Off ratios getting enhanced performances as transistors.
