In at least one embodiment, a TFT includes: a first capacitor formed of a first capacitor electrode connected to a source electrode and a second capacitor electrode; a second capacitor formed of a third capacitor electrode and a fourth capacitor electrode; a first lead-out line; a second lead-out line connected to a gate electrode; a third lead-out line; a fourth lead-out line; a first interconnection; and a second interconnection. This realizes a TFT which can be easily saved from being a defective product even if leakage occurs in a capacitor connected to a TFT body section.

A distance (d1) from an edge of a first region (R) at places (D) where branch electrodes (4b) extending, which branch off from an electrode line (4a) of a second source/drain electrode (4), start to overlap with a first region (R) to the electrode line (4a) is 5 μm or more. This realizes a TFT including a comb-shaped source/drain structure that enables easy repair of a source-drain leakage.
