Organic insulator composition including a hydroxyl group-containing polymer, dielectric film and organic thin film transistor using the same

摘要

An organic insulator composition including a crosslinking agent and a hydroxyl group-containing oligomer or hydroxyl group-containing polymer is provided. A dielectric film and an organic thin film transistor (OTFT) using an organic insulator composition are also provided. A dielectric film may include a compound having hydroxyl group-containing oligomers or hydroxyl group-containing polymers linked by crosslinking using a crosslinking agent having at least two vinyl ether groups. An organic thin film transistor may include a gate electrode on a substrate, a gate insulating layer on the gate electrode, source and drain electrodes on the gate insulating layer and an organic semiconductor layer contacting the gate insulating layer, wherein the gate insulating layer includes an dielectric film as described above.
