PROBLEM TO BE SOLVED: To provide a thin film transistor that is capable of maintaining high characteristics even after exposure in the environment of high temperature and high humidity, and also provide a wiring board comprising the thin film transistor, a display device, and electronic equipment. SOLUTION: A thin film transistor comprises a source electrode 3 and a drain electrode 4, an organic semiconductor layer 5 which is provided in contact with the source electrode 3 and the drain electrode 4, a gate insulating layer 6 which is provided in contact with the organic semiconductor layer 5, and a gate electrode 7 which is insulated from the source electrode 3 and the drain electrode 4 via the gate insulating layer 6. At least one of the gate electrode 7, the source electrode 3, and the drain electrode 4 is comprised of a porous film that is mainly composed of a conductive material. COPYRIGHT: (C)2005,JPO&NCIPI
