ORGANIC THIN FILM TRANSISTOR AND ORGANIC THIN FILM LIGHT EMITTING TRANSISTOR

摘要

In an organic thin film transistor, at least three terminals, which are a gate electrode, a source electrode and a drain electrode, an insulator layer and an organic semiconductor layer are arranged on a substrate, and a current between the source and the drain is controlled by applying a voltage to the gate electrode. The organic semiconductor layer includes a specified organic compound having an aromatic heterocyclic group at the center. Light is emitted by using the current flowing between the source and the drain, and light emission is controlled by applying a voltage to the gate electrode. Response speed is high and furthermore, an on/off ratio is large. An organic thin film light emitting transistor using such organic thin film transistor is also provided.
