摘要:
An organic thin film transistor that can control the threshold voltage and reduce leakage current includes: a gate electrode; an organic semiconductor layer insulated from the gate electrode; a source electrode and a drain electrode insulated from the gate electrode and electrically connected to the organic semiconductor layer; a gate insulating layer interposed between the gate electrode and the organic semiconductor layer; and a hole control layer that is interposed between the gate insulating layer and the organic semiconductor layer. The hole control layer includes a compound having a hole-donor group or a compound having a hole-acceptor group.
