Thin film transistor, fabrication method thereof, repair method thereof and array substrate

A repair method of a thin film transistor, for repairing a short circuit between a source electrode and a drain electrode of a thin film transistor,

• the source electrode of the thin film transistor comprising a first source electrode portion and a second source electrode portion independent from each other, and/or, the drain electrode of the thin film transistor comprising a first drain electrode portion and a second drain electrode portion independent from each other, the source electrode being connected with a data line and the drain electrode being electrically connected with a pixel electrode,
• wherein the repair method comprises:
• cutting off a connection between the first source electrode portion and the data line in the case that a short circuit occurs between the first source electrode portion and the drain electrode;
• cutting off a connection between the second source electrode portion and the data line in the case that a short circuit occurs between the second source electrode portion and the drain electrode;
• cutting off a connection between the first drain electrode portion and the pixel electrode in the case that a short circuit occurs between the first drain electrode portion and the source electrode;
• cutting off a connection between the second drain electrode portion and the pixel electrode in the case that a short circuit occurs between the second drain electrode portion source electrode;
• cutting off the connection between the first source electrode portion and the data line and/or cutting off the connection between the first drain electrode portion and the pixel electrode in the case that a short circuit occurs between the first source electrode portion and the first drain electrode portion;
• cutting off the connection between the first source electrode portion and the data line and/or cutting off the connection between the second drain electrode portion and the pixel electrode in the case that a short circuit occurs between the first source electrode portion and the second drain electrode portion;
• cutting off the connection between the second source electrode portion and the data line and/or cutting off the connection between the first drain electrode portion and the pixel electrode in the case that a short circuit occurs between the second source electrode portion and the first drain electrode portion;
• cutting off the connection between the second source electrode portion and the data line and/or cutting off the connection between the second drain electrode portion and the pixel electrode in the case that a short circuit occurs between the second source electrode portion and the second drain electrode portion.
