Thin film transistor, method of repairing the thin film transistor and displaying apparatus having the thin film transistor.

A thin film transistor is connected to a picture element displaying electrode formed on an insulating base plate so that a voltage is applied to the electrode. The thin film transistor comprises a gate electrode, one or more drain electrodes connected to the picture element displaying electrode and a source bus line which -applies a voltage to one or more source electrodes connected thereto, the source bus line functioning by itself as a source electrode, wherein the one drain electrode is formed between the source bus line and one of the one source electrode connected to the source bus line, or between the source electrodes adjacent to each other.
